Super weird to ask, but I need advice :(

Ok, everyone this is a little weird to ask but I am seriously at a loss here. My husband has refused to have sex with me for the last like 6 months. We had sex once on vacation at this time but he was completely drunk. I've tried talking to him to see if he's uncomfortable doing it with me because i'm pregnant and he says no there is no reason. I've tried making the first move and he will completely turn his back on me. So, yesterday I told him I feel so unwanted and really don't understand what's going on. He said he just get's tired from work or doesn't feel comfortable doing it because we live with my parents at times. But before when we were dating he used to be the type of person that wanted it every chance he got 3x a week anywhere. He never cared if we were sneaking around to do it and I was the one who was always thinking it was crazy. Well yesterday we decided to go walking in the canyon and an argument started about this and he told me he was tired of my sh*t. I told him I was no way trying to fight with him but I feel so distant and being pregnant just makes it worse. I feel so ugly and unwanted. He told me yea yea shut up already. He went on about how I ruin his days. So I told him that if I really made him unhappy to just tell me, that in no way was I going to force him to stay with me. Well, his response "well why don't you go get dick somewhere else since that's all you cry about." I just responded with ok and asked him to please turn around. He said no that we were going to at least get some fresh air so we ended up walking around the canyon. Super quiet both of us not saying anything to each other. Towards the end he grabbed some water and splashed it on me trying to play around and started trying to almost flirt with me a little. Then the night came and I asked if I could cuddle with him in bed. He instantly said no that he was tired and turned around. So like every single night I just turned to my side of the bed and fell asleep a little after him. He ended up waking up in the middle of the night, he shook me a little and whispered "hey, i'm tired right now but i'll wake up a little early for work and we can do something." (Now this is after his friends messaged him that if he had sex with me then it would probably get the baby to come sooner) (I'm 36 weeks pregnant and have been having bad contractions) But I told him ok and just hugged him. So this morning I could hear his alarm going off but he wasn't getting up. So I woke him up and he just said "Sh*t i'm late.... F**k it." then laid back down. I started to touch him and asked him if we were going to do something and he FLIPPED OUT!! He started yelling at me that I don't give a Sh*t about anything or him being late. That no he is not in the mood to do anything with me. As he was changing I told him I wasn't trying to fight at all that I had just asked and he told me to SHUT UP! I couldn't believe he was that rude. .. When I asked him what? He said "oh, do you not understand what shut up means?" STOP TALKING.. you ruined another one of my days"! He then left to work .. didn't even say bye. I am so confused now as to what to do. A part of me is even wondering why i'm in a relationship with this guy. I need some advice guys thanks!
