TIFU By making out with my mother in law

English isn’t my main language sorry in advance

I(33m) kissed my mother in law(58f) and it led to us having sex. I was married to her daughter, Jade(33f) for 6 years, dated for 4 years. We had her parents, my in-laws, move in with us about 5 years ago because of her dad’s(63m) declining health. At first I was kind of hesitant with them moving in because I enjoy our privacy and we’d lose a workspace, but it was fine, we weren’t in bad terms or anything. Over the past couple of years, we’ve all gotten closer and felt like a whole family, my MIL Em, is very kind and took care of us when we were too busy with work to cook or clean and my FIL Gary, helped with what strength he could muster, he was a jack of all trades and real old school kind of guy.

Jade took her dad to his doctor’s appointment, and got hit with a semi truck. When I heard the news, I dropped everything and raced to the hospital. Gary died on the scene and Jade was in critical condition. We were all hoping and praying that Jade would make it, but she passed a couple of hours later. I was inconsolable. I didn’t want to let go of her hand. We had so much ahead of us, we had so many plans. Em was even worse, they spent almost 40 years together. We held their funeral on the same day and we had them buried next to each other. That was a year ago.

Em would break down often and I would console her. Last week, she said that she was planning on moving out and live with her eldest daughter, but I told her that it’s fine, she can live here as long as she wants, she’s family afterall. And then she hugged me.

And this is where I fucked up. I was wiping her tears while I was hugging her and I leaned down a little bit so can be eye level but I leaned down too much and accidentally kissed her. I backed up and I apologized and told her that was not my intention. Y’all. I was embarrassed. She said “well, I don’t blame you. I know I kinda look like my daughter. Don’t be embarrassed, I didn’t mind and I’ve been feeling lonely. I guess I still got it, as old as I am, hahahaha” (it’s true tho, she always took care of herself) we kissed again. We were making out like a couple of teenagers. We didn’t even make it to the bedroom. We had sex right there on the couch.

And that’s when post nut clarity hit. I said noooooo what have I done???? I fucked up bad! I stared at Em and she stared back at me and we agreed to not speak of this to anyone. Our loneliness got the better of us. That was last week.

So, she decided to visit her youngest daughter and stayed for a couple of days to clear her head. I drowned myself with work and personal projects to distract myself. When Em came back home, she wanted to talk to me about what happened the other day. My stomach sank. She said told me she appreciated everything I’ve done, but what we did was wrong and an insult to her late husband and her late daughter, my late wife’s memory. Which I completely agree with. She moved out yesterday and is now staying with her youngest daughter. Now I live in this house by myself, with a couple of dogs and burned the bridge to my last connection to the love of my life.

TL;DR: I had sex with my mother in law because we were lonely widowers and now I’m alone.
