With or without him, depending on how bad the situation is, I'd leave. He has to understand that you need to be as comfortable as possible and that his mom is a stress trigger which could be harmful to your pregnancy. You have to start doing what is best for you AND baby. If he can't see that, tell him that you hope he'll be happy with his mother!

I've been living with my bf and his mom for 3 years....she starts shit with me all the time and takes over his son yet says she's not interfering

I lived with my boyfriend and his mom and left like a month ago but it was because of his grandma who's Satan's spawn. She lived a few floors up and was always in their room and she was so rude and mean to me for literally no reason and I was either gunna flip on her or just leave do I left. We're still together but now we live an hour and a half apart which sucks but luckily we're moving into a place in 2 weeks.

she controls everything with his son now and he agrees that he's gonna say something but usually when I tell him that's why we should leave he tells me to shut up

amen
