Boyfriend is always a dick?

Chellsey
So I'm 6 weeks pregnant , and before we got pregnant we were on the verge of a breakup . We live together and We haven't been getting along and it seems we can't talk to each other without being rude or giving attitude or dirty looks , his tone and looks make me angry even though I've brought it up many times . Then he loses it all we do if fight and yell at each other and I spend at least 3 nights a week on the couch due to us not talking or getting along . This is making our sex life ruined and we haven't had sex since I got pregnant . Now that's an issue and he freaks on me for it . But I have no desire to "jerk him off or suck his fkn cock" like he wants me too if I don't wanna have sex. Some how this is always my fault . Why would I want to touch you if we aren't Getig along or talking let alone get you off . Miscarriage runs in my family he knows that and I spend the majority of my days crying over him or fighting with him . I just dont know what to do anymore because he sees its always me in the wrong and finds himself to be perfect . It's so frustrating and I just don't know what to do anymore . 
UPDATE - he just said the amount of dicks I've sucked and fucked in my life and I can't touch his . Wow that's calls for relationship to be over in over this shit . That's no way to talk to the mother of your child and expect to be around .
