Run for the hills. Miserable fucks - and he probably isn’t as available as he is trying to seem if his ex gf is still in the picture. My guess is he is probably a serial liar and hasn’t been a good partner to his ex. His mother is probably just looking out for his best interests and you are being kept in the dark about a whole lot of shit.

I would talk to my boyfriend and let him deal with it. But if he didn't put a stop to it immediately I wouldn't stick around.

Run for the hills, with or without boyfriend

Can we have more info? This seems juicy is all🤷‍♀️

Hmm happened to me. But was messy. And boyfriend was totally under MIL thumb and did everything she said.
I left town after taking out temporary restraining orders because she was legit a psycho.
Both were challenged and lifted as I did not show up to court as I left town.
Boyfriend followed me, and him and MIL completely cut all contact. I don't know what else was going on in that family. Was really really fucked up and sometimes i worry if enough time passes she'll come back on the scene like nothing happened and she didn't try to get a gang of family members to rough me up a bit.

Honestly, is being with him worth the drama?
Is he doing anything to stop it?
Will this be an ongoing issue

You can't choose your family, but you can choose your family in-law.
I love my husband dearly, but his family is so awful, I sometimes wish I would have chosen a partner with less family drama!
His family drama leaks into pretty much every aspect of our lives.
Probably a very unpopular opinion, but unless he has agreed to cut them out and run away with you, I would leave him.

Been in your shoes and if I had my time again I'd walk away. Not worth the drama and it speaks absolute volumes about his mother. Do you want to be dealing with that for potentially the rest of your life?

Honestly, it would depend upon on what my boyfriend did about it. I would put up with behaviour like that 0% and see it as his job to ensure it stopped. I'd also consider whether I wanted to spend the rest of my life potentially related (MIL) to someone who would behave like that towards me.

Tell my boyfriend and let him deal with it
