Do I sound petty and childish ?

We live with boyfriends mom. This whole pregnancy, she ALWAYS has something to say. 7 weeks pregnant, she was complaining I was too “skinny” , asking me where my bump was, why I’m not showing, etc. mind you, I had gotten out of an extremely abusive relationship a year prior and only weighed 85lbs and struggled very badly to get my weight up. She always had comments that I need to eat, I’m starving my baby, I’m doing this, I can’t do this, I should do that, etc. shortly after I found out I was pregnant, his brother in the navy and his girlfriend announce they’re pregnant. Due feb 20. I’m due March 14.

They have been comparing us the whole time. She’s having a boy and I’m having a girl.

My bf just called his brother, as his mom went up there to see them and hope their baby comes. And his mom takes the phone and starts with her shit.

“Oh she only gained 30lbs this whole pregnancy” she knows ive gained 60lbs and she straight up said I gained that much because I eat out all the time and eat nothing but candy. Like we don’t even see each other every day. She doesn’t know what I do. I’m too skinny for her, I gained too much for her. I’m eating too much, I’m not eating enough. And then she says how she’s always up and moving and carrying bags and doing this and that, which is so beyond hypocritical.... I’ve had complications with my pregnancy and have a friable cervix, I can’t go up and down stairs like that. And without fail EVERY SINGLE TIME I use the stairs or carry something, my bf AND HER yell at me and say how I can’t do this and can’t do that. But she’s over there making me sound so beyond lazy when I’m not. I clean every single day, laundry, bathroom, clean up after my bf because he can’t ever, I’m ALWAYS getting up and doing something. It frustrates me so much because I’m now back at my weight that I was before, when I was happy and healthy and of course someone has to bring me down about it. I felt so happy. Like I wasn’t too skinny for everyone. Now I gained too much and it’s always “its okay, you’ll lose it” like ???? I don’t want to lose it. I changed my life for my bf and left my home just because he doesn’t want pets around our baby and I’m so miserable here and he has no idea or understanding why. He argues with his mom every single day and everytime they see each other and then wonders why I’m so awkward. Like I don’t know Spanish and they’re always going back and forth screaming in it and I’m just in the middle not knowing what to do and then when I’m quiet he always asks me “do you have something against my mom?” Like ???? You just make it extremely uncomfortable for me! Sorry for long post. Rant over. Just so stressed.
