Feeling so sad. Need to vent.

So i just got home, i was hanging out with my 11mo baby and boyfriend .. we were in the car and i heard him commenting over a girl he saw on IG, and i felt kinda bad cause he rarely says something to me.. then we got home and said how pretty the girl of the movie was, i got mad again and felt bad. Yesterday i saw he liked a girls photo , he is always seeing girls on ig.. felt bad again. I felt and feel so ugly and worthless. It might be dumb but i feel so ugly. After saying the girl of the movie was hot he said “did you saw the foreign girls from india at the store?” And i say, yeah they were pretty (i meant that) and he respond “yea they were i liked one” and i feel so miserable and ugly and all that stupid shit and now im crying like an asshole. I feel so bad. So bad cause i cant do my makeup i barely know how but this girl was so pretty and her makeup was pretty aswell, i feel so ugly cause i barely has cute clothes that he likes, i feel ugly cause i have shor hair and she had this way long hair. I feel so ugly with my strech marks on my belly and all that extra skin that my pregnancy left even tho im skinny. I feel so ugly cause he is always being rude and making jokes about me. Feeling so sad lately, so insecure.. ive always been but he made me be more cause our past problems. I hate him so much . If he likes many girls around us, why he doesnt fucking go away with one and leave me and my baby alone. I want him to leave but at the same time i dont.
