AITA for calling out my aunt for celebrating my father’s affair baby while ignoring other kids from family infidelities, and then blocking his entire side of the family?

Names changed for privacy.

My parents, Miguel (63) and Elena (55), have been married in the Catholic Church for decades. They are still married in the eyes of the Church, because my father has never had the marriage annulled. That means in the Church’s view, my parents are still husband and wife — but in September 2024, my dad started a relationship with Laura (45), a woman who at the time was married to someone else. By July 2025, they already had a baby together. Just last month.

Laura is not the saint she presents herself to be. She has around 10 lawsuits against her, but still parades herself as extremely devout and moral. My dad’s side of the family, the Riveras, are very Catholic and talk a lot about values — but when it comes to Miguel and Laura, they’ve conveniently looked the other way. My dad even tells people he’s “been alone for 10 years,” despite living with me and my mom until late 2024. I want to make it clear that I (28, F) have no relationship with Laura as I cannot… morally and emotionally I cannot accept this. And for my entire life it’s only been seeing my mom and dad together and out of nowhere my dad wanted me to just accept his affair to a married woman? I should also note that Laura and my dad met because Laura’s husband was my dads employee. I should also note that Laura came into this country as a tourist, got married to her now ex-husband for a green card, and then saw my dad who was a citizen (unlike her resident ex-husband) and who had money, and decided to have an affair with him. She came into this country in 2023, got married to the guy in early 2024. I actually met her once when I went to church with my dad and saw that she was there with her husband. She said she wanted to get married via the Catholic Church with him to not be in sin. Anyway, this was in August of 2024. In September, the affair started. In October 2024 it was made public. In November 2024, my dad got an apartment with the woman and in December 2024 she was announced to be pregnant. Given all of this, I had her investigated which is how I found out she has 10 lawsuits against her in her home country, and has even had her car taken from her for not paying.

For a few years now, Miguel (my dad) has been financially supporting much of the Rivera side: paying bills, giving cash, helping them out with favors. They’ve all benefited from his generosity, and now they’ve rallied behind him and Laura while pushing my mom and me aside completely. Flashback to ten years ago, we did not have a lot of money and so this family aka my dad’s siblings didn’t even give us the time of day.

Here’s where the hypocrisy hits hard: the Rivera family has a long history of infidelity, and they have never gone out of their way to publicly celebrate the kids that came from those affairs.

My aunt Rosa (the aunt in question, my dad’s sister) lived through her ex-husband cheating and having a child outside the marriage. Rosa’s daughter’s ex-husband also cheated and fathered a child. My uncle Luis (my dad’s brother) cheated on his wife and had two children outside his marriage. My grandpa also had cheated and had children outside of marriage. He passed away a few years ago, but my grandma prides herself on saying that those children are not my grandpas kids. Aunt Rosa’s ex-husbands kids are not biologically related to us, but if Rosa truly believed in “all children are blessings,” she could have celebrated them, she didn’t. Which is understandable because she was cheated on, but this child she posted about what was product of my father’s infidelity. Uncle Luis’ children ARE biologically part of the family — and yet, no glowing Facebook tributes, no “blessed family” captions, no public celebration for them. In fact, the family ignores their existence. Why? Because Uncle Luis doesn’t have a lot of money to support everyone.

Fast-forward to last week: Rosa posts a big Facebook album celebrating Laura’s baby turning one month old. Heart emojis, blessings, proud captions, etc. this was the first post ever publicly acknowledging my dads affair and thus this child. I couldn’t believe the hypocrisy. For one, aunt Rosa was supposedly my mom’s friend and sister-in-law.

My mother sent me the post. She was sad and angry all over again, just like she was in the first few months of my dad’s affair. To be fair it hasn’t even been a year since he left my mom. And so, since my aunt Rosa made it public on Facebook for everyone to see, I commented:

“Aunt Rosa, what about the children from your ex-husband’s infidelity? What about the child from your daughter’s ex-husband’s infidelity? Where are those kids?”

My point wasn’t that children from affairs shouldn’t be acknowledged — it’s that this sudden public joy isn’t about loving all children equally. It’s about celebrating Miguels (my dads) infidelity while conveniently ignoring every other similar situation in the family’s history. Why? Because my dad has a lot of money and financially supports them all. Also it’s that she herself was cheating on, but doesn’t care when it was my mom who was cheated on to post this.

Cue the fallout.

My cousin Melanie DMs me. She starts with “I know you’re hurting” and says blocking people might be for the best… and then blindsides me by accusing me of spreading a rumor that another cousin, Pedro, was the father of Laura’s baby. This is 100% false. I told her I never said that, and that my half-sister Fabiola (who has lied about me before) likely made it up. This part is a bit messy. And I can explain here but basically Pedro (28) used to work with Laura and they’d travel for work and stay in the same room together to save money. Pedro himself told us this. My half sister is 18 years older than me and is from another of my dads affairs. Except he didn’t cheat that time around. He was 16 when he had her with a servant at my grandmothers house who was 24. Since then Fabiola has been raised by my grandma as if she is her daughter. Back then my father didn’t have a lot of money individually. Anyway, Pedro worked with Laura and he would tell us how obsessed she was with him. But I never said that Laura’s baby was Pedro’s. Never. I did hear Fabiola say that Laura was obsessed with Pedro. While I don’t know if the baby is my fathers, I think it is the woman’s ex-husbands baby. As no DNA test has been done since by father is a proud man. My dad also paid for Laura’s divorce by the way. Also Pedro was considered a friend of mine, a friend of my husbands as well. We are the same age and would go on double dates with him and his wife. I would never speak ill of my cousin Pedro as he has been nothing but sweet.

That was the last straw. I told my cousin that I have never and will never say that about Pedro. That it is surprising to me that she would believe that lie. But ultimately I realized that she won’t change her mind because she thinks I am on a “war path” for making the first public comment I have ever made about my dads infidelity. And I only made it because my aunt made the post.

I then decided to block everyone on my dad’s side — cousins, aunts, uncles, even my grandmother. My grandmother is also not innocent in this as she herself has said that she will never meet my Uncle Luis’ kids born out of wedlock, yet because my dad financially supports her, she is all in with my dads new baby. I’m DONE with the gossip, favoritism, and rewriting of reality to make themselves comfortable. My mom has also blocked them.

Now the Rivera family narrative is that I’m bitter, angry, lashing out, and “hurting innocent people,” not that they’ve erased my mom and me while embracing Miguel’s new life and ignoring their own past hypocrisy. This in particular hurts for me as I have always been closer to my father. My mother and I have never been as close as we are now. But now it seems like it’s my mom and I against the world. My husband is also here, but understandably he doesn’t get involved, but he has also blocked my family. He says that I should have commented “you are only posting about this baby because my dad financially supports you” as a slap to the face. My husband said either go big or go home. I, however, did not comment that, as the first comment was made at an impulse decision after my mom sent me the post.

They will probably always believe I said that false rumor about Pedro, no matter what I say. But I know the truth, and I’m done trying to prove it. And they will think I am the bad guy for not saying what my dad wants to hear.

I should note that I still have somewhat of a relationship with my dad, but we only see each other sometimes and we never talk about his other family. It’s the only way I can have him in my life now. Whereas before, I was, as they say, the apple of his eye.

So… AITA for publicly pointing out my aunt’s public selective celebration of my father’s affair baby on Facebook, and then cutting off his entire side of the family?

TL;DR: My Catholic-married dad started an affair in September 2024 with a woman who was also married, and by July 2025 they had a baby. Family has never celebrated kids from other affairs in the family, but gushes over this one. I commented on my aunt’s post pointing that out. Cousin accused me of spreading a false rumor, ended friendship. I blocked them all.
