Need relationship advice💔

Hi ladies so i just need to vent. My boyfriend who is also the father of my child we’re having sex tonight and it was very awkward and he made me feel like complete crap about myself. I’m 4 months post partum this month so I’m having a hard time with my body image as it is. He was staying up all night sence he got laid off from work wicked late always playing video games and bairly ever helps with our daughter. I’m so tired of feeling like I’m doing this by myself. I beg him to help and it’s always an argument and it’s not fair to our daughter either. So anyways last night he came to bed at 4 am all handsy trying to have sex. We havnt had sex in WEEKS so i was like okay let’s do this lol. So we’re going at it and he never goes down on me sence i was pregnant tonight was the first time in months and he stopped and came back up i was fine with it. So then 2 mins later he just stops and lays down and says “I’m to tired” like ok... didn’t you just wake me up? So he tried again and then he said you need to cum now this is ridiculous just hurry up and get this over with... things in our relationship havnt been great for a while and we separated when i was 5 months pregnant. The passion in our sex life is completely gone. Ever sence i came back things havnt been the same and i feel like the only reason I’m here is because of our daughter and a “warm body”.💔 I’m honestly so hurt and feel so bad about myself now. He doesn’t even kiss me anymore or give me a hug he constantly pushes me away litterally not just emotionally. I just don’t know what to do. Apart of me wants to move on and go back home and another wants to stay and make it work for our daughter. Another thing is i don’t think I’ll find another guy like him he was so sweet in the beginning but he has changed for the worst💔
