I feel so insecure & stupid ๐Ÿ˜”๐Ÿ™ˆ

It's been like this since I was showing like around 5 months, but has only gotten worse. My bf never wants to do anything (have sex) with me anymore, he doesn't even make out with me anymore. It makes me feel like shit & wonder why he isn't attracted to me anymore. He used to never leave me alone & I used to have a nice body & being pregnant 39 weeks makes me feel even more insecure since he won't touch me. Everytime we have done anything, the few times we have, was because I had to start off by giving him a bj or asking for it which makes feel crappy cause I've never had to ask or have been rejected like that besides now. The reason I'm pregnant is because he was basically a nympho before & wouldn't leave me alone. Now I'm pregnant with his baby & he makes me feel like I'm disgusting. I tried to get him to do something tonight & he knows how miserable I've been, since I'm due in 3 days & ive been trying everything I can to have this baby already but sex since I can't get him to, he still doesn't seem to care or try. I asked again it took a lot for me to, cause of fear of being rejected & he gave me a lame excuse like, " he just went #2 in the bathroom & he needs to shower" I said okay then shower, & he was like okay & started playing his stupid game on his phone trying everything to ignore taking a shower then finally gets up & then acts like he's gunna shower & goes pee & then laughs like its funny. I switched to the opposite side of the bed & started to cry & he had nerve to ask me why & I told him I'm tired of him making me feel like this that he has a problem & I can't control that I'm pregnant & don't look the same. I don't even want him to touch me anymore, after he treated me so shitty my whole pregnancy I don't even feel like I can be with him anymore. He can't even give me a reason why or tell me why he is constantly rejecting me I don't understand ? I'm 23 & he's 22 he used to have such a high sex drive it would annoy me & now I'm in this situation & I feel so unattractive & humiliated. I need advice. I want to crawl in a hole, & it sucks cause I'm 39 weeks pregnant it's not like I can just jump up & move on/:
