Advice Please on SO

So confused about what to do. been with so for about 4.5 years currently pregnant with our first child at 33 weeks . He turned round tonight and said he doesn't love me but loves me because I'm carrying his child. He says he can't tolerate me at the moment because of my hormones and because I don't want to cuddle or or push him away when he wants to cuddle. I admit that's true but I don't do that all the time. I've explained it's not personal but he says he can't help but take it as it is. He also commented that we haven't been intimate often, yet when I try to initiate he doesn't want to and vice versa and it's so painful for me that thought itself is bad enough. After making all that clear I've made it clear that he wants to go he can, he then says he loves me and that he doesn't want to leave and also confesses that he has been lying about not smoking when he told me he stopped 8 months ago out of fears he'd disappoint me. Hes had quite a few tonight and I'm not sure what what to think or do right now I just feel sick.
