please

I'll start from the beginning; 

Me and my boyfriend- well before he was my boyfriend, we hung out for about 3 weeks before we started dating. He asked me to be his girlfriend, I said yes. He is sweet, respectful, kind, honest, loyal, and so on. How could I pass that up? We have been hanging out since middle of March & started dating April. It's been about 6-7 months total I guess that we have known each other. He then was over at my house constantly & we hungout literally EVERYDAY. (Didn't bother me)  Then we got pregnant. I'm about 5 months now. We decided it would be a good idea to move in together.. Well, here's the problem. 

We do get along for the most part. But here's the downfalls, 

He doesn't trust me at all..why? I have no idea. He gets upset when I like a guys status on Facebook, he gets upset if I even look towards a guy in the store (Not even on purpose), he gets upset if I post a picture without him in it, he gets upset if I post a status- automatically thinking it's about another guy or about him. If I have a scratch on my boob or butt he thinks it's from a guy, he gets mad at ME if a guy likes my status, photo or messages me. ( I don't even reply ) it's not even my fault & I can't do anything about that. He thinks I'm cheating on him and he doesn't feel loved if I don't feel like having sex with him. (My hormones have been up and down with this pregnancy) and he constantly thinks I'm lying to him and cheating on him. I haven't done either of those things and it's killing me having to prove it to him..we also kinda lost things to talk about. We literally drove an hour into town - didn't talk. Drove back home, barely talked. Got home- he passed out. Like wtf??? I get he works 5 days a week and that's what he blames it on ", but really ?! It's annoying everyday he comes home and accuses me of stuff, & he never wants to get up and do adventurous things, yeah I'm pregnant and want to relax most of the time but I have a dog and I used to take him hiking and now I've noticed I don't do that as much anymore:( 

I'm wondering what should I do??!!! 

Should we end it ? , should I try and fix things? Am I just hormonal and exaggerating? Are we not a good mix? Like idk what's going on. We used to be so good and now I feel we have faded. He doesn't do anything wrong other than those two things. Other than that he's straight up perfect. 

I'm so confused.. 😢
