MIL tries to convince all her family that I stole her son from her

Hi everyone!! I’ve been wanting to post on this sub for a long time since my MIL is a piece of work.Apologies for any mistakes or holes in the story,I’m east european so this all translated,also I’m writing this at 4am on mobile.

So,me (18F) and my boyfriend (19M) have been together for almost 2 years.We have known each other since 5th grade,became good friends somewhere in elementary school but only dated since 10th grade,with a break during the summer so we can solve some personal issues.

Initially,his mother liked me and wanted to meet and have a conversation but it all went downhill last year and I didn’t recognize her and I didn’t greet her.Since then I’ve been disrespectful in her eyes.From that moment she started picking fights whenever me and my boyfriend hang out.Last year I moved alone into my parent’s apartment and I proposed to my boyfriend to have sleepovers once a week since we didn’t have a car yet and we only hung out outside at malls.He was on board but on the night he had to come his mother started guilt tripping him about “leaving her all alone” or “not caring about his sick grandma and how not having him there will kill her” (BF lives with his mom and grandma).The plan abolished and we only hung out during the day.

Around this time she started insulting me to my boyfriend in many ways.Some examples are “dr*g user” because she heard me and BF laugh on the phone when she tried to guilt trip him again, “cultist” because ,apparently, a man can only leave his mom when he’s in a cult, “golddigger” because my boyfriend brought me gifts for my birthday and anniversary, “bitch” because I will for sure cheat on him, “peasant” because my parents moved to the countryside to work in agriculture, and many others.

Of course,my boyfriend started picking fights because of this behaviour with her and all the hopes of a relationship with her crumbed.Meanwhile,FIL bought him a car and we started going away on holidays or have sleepovers on occasions (like my birthday,new year,anniversary etc).

Fast forward half a year since I want to get to the point of this story (there haven’t been any major conflicts during this time,only insults mostly) me and BF finished our final high-school exam,he turned 19 and we graduated.We had a sleepover for his 19th birthday where she tried to guilt trip him again saying “instead of starting this new chapter of your life together,you go and start it with somebody else” which raised alarm bells for both of us because of emotional incest bs we have seem all over the internet with boy moms.BF got an incredible ick from this and came over with no problems (he got better over the months with managing her guilt tripping).A week later, we decided to do the big step with a form of “moving together” (staying together from Thursday to Monday every week),which she has known about since I got the apartment.She freaked out and tried everything to make him stay home,bringing his grandma into this and everything.The week went fine and he only had to deal with a ton of guild tripping and false crying when he got home.

A crucial detail is that she’s a singer but barely gets any concerts (maybe because she sucks but idk).She signed a contract for a concert (Saturday) across the country and she expected her son to drive her there without any confirmation.BF said that she won’t drive her but she started again with immense guilt tripping,crying, screaming, basically throwing a tantrum.The same night we almost fought because he’s tired of this behaviour and just wants to get it done so she can leave him alone but im against the idea of “keeping the peace” when she keeps pulling conflicts out of nowhere. Same story,BF goes to pick me up from my parents on Thursday so we can go home but unexpectedly his mother calls me (she got the number from his phone when he was sleeping and threatened to call me and my parents many times).The convo went like this (shortened because I don’t remember every word,we talked for 4 minutes)

“Hi Eli”
“Hi?”
“I’m bf’s mom”
“OK?”
“I think you heard that i signed a contract for X city and bf needs to drive me for that.He told me he can’t drive me,his mom,because he had to attend some party and stay with you for the weekend??”
“Yeah? I don’t understand why you’re calling me and how you have my number.Im pretty sure this is a dispute with your adult son,who can choose for himself,not with me.And im pretty sure he has no obligation towards something that wasn’t communicated and agreed upon with him”
“Don’t you hear yourself ?! He can’t drive me because you forced him to leave his mom hanging.And don’t you raise your voice at me”
“I’m not raising my voice and I don’t think your son can be forced somewhere at 19.You can go by train,I can send you the links for booking a ticket if it’s so hard to find alternatives.And don’t try to parent me,not even my mom does it and you think you can?”
“SO YOU WANT ME TO GO BY TRAIN WITH LUGGAGE FOR AN ENTIRE DAY WHILE HE DRIVES YOU AROUND.THAT’S IT,IM CALLING YOUR PARENTS TO TELL THEM ABOUT THIS”

Mind you,i was respectful during the entire conversation,just fed up with her drama,especially calling me to complain about her non-existent relationship with BF.After this I texted her that my parents are busy people and to not even try to bother them with this since they’ll take my and BF side.She continued to text me about how she is his mom,his priority etc.One text that stuck was “I raised him and it would be nice for this to do the same” which had us disguted once again.The conversation ended with a text from me telling her to lose my number and to stop this whole show because we are all adults.

Meanwhile BF called her, told her she’s out of line,stupid and to stay away from his relationship.She didnt talk with him for the entire weekend but friday afternoon FIL called because MIL called him to meet up and discuss this.MIL told FIL that bf ran away from home,that he disrespected her and encouraged me to do the same,that she has no one by her side now and if he can drive her to her concert on Saturday.

Saturday morning,his cousin/aunt called BF and asked to meet up to talk.They met up in the evening and discussed the whole situation.She insisted on him still being by his mother side but also understanding how difficult she is.That we can be together but family comes first or that she wants to meet me because she doesn’t believe I am as bad as MIL makes me look.

BF went home yesterday but MIL said she’s too tired to talk (yeah sure) and that she will have a conversation with him tommorow.

Overall,boyfriend is pretty overwhelmed and mad and im just upset.I have an ok relationship with FIL,we talk on video call from time to time when BF stays at me and kinda thats all.He’s not a reliable person in this whole ordeal world we keep our distance.His aunt is okish, I’ve never had conversation with her but she’s from my countryside so I heard things about her from my dad.Might come update tommorow if they actually talk,but I doubt it.
