Insanely triggered by my roommate.

NPR but, I have an eating disorder and am in recovery now, i had EDNOS because I didn't meet criteria for Anorexia or Bulima but since I had problems from both they said EDNOS. I have been in recovery almost a year in December, because I got pregnant in February and decided I wanted to stay better for the tiny thing growing inside of me. But now at 29W1D it's getting hard because well one I'm gaining weight, I've always been bigger but I was less than I am now, and two because my roommate has a mild form of an eating disorder, and always complains he's fat and he can't eat cause he'll get fat (he's almost 180 pounds but is skin an bones because he's 6'2) and it is getting to me and I dont know how to deal. I don't want to go back to purging (through throwing up and laxatives and diuretics) or starveing for weeks before having to eat or pass out, I am a mom now and want to be healthy for my son. Its just getting hard to not do the bad behaviour because 1 it's around me all day every day and 2 because I have that problem and have since I was young. How do I tell my partner that it bothers me and I can't deal with the comments, or how do I bring it up to the roommate? I just can't deal much longer.

And please dont tell me I'm a bad mom because I'm having these thoughts or that I'm struggleing still.

Update: I talked to my partner and she thinks I'm just saying it because i dont like him. He's her best friend I get that but still. I feel like nothing I can do is right. I talk about my feelings and I get bitched at, I don't talk about them and i get bitched at.. I love my partner to death but sometimes she's an ass. She apologized and said she realizes it actually does bother me but still.
