feeling confused

So my husband and i have been fighting a lot lately today bcs he's so distant and doesn't seem as caring as before. we kinda made up but didn't really talk about it or anything he just apologized for calling me bad names but said im a drama queen after I told him maybe I should just move out of we're going to continue to fight and he doesn't see what he's doing is not ok. bcs I feel like I need his attention and he feels he does give it to me but it's been months he stopped texting me while he's at work and before he would all the time I don't get it I know he's busy but a text here and there to check on me is not hard I'm 32 weeks pregnant and Have been so emotional and been feeling so alone. How is that's so hard. He's always at work never makes time for us he even works Saturday's. Let alone time alone for me and him and he feels he's not doing anything wrong. And I understand that hes busy at work but why is it that before he would make an effort and now he doesn't that's what I don't understand. And he says its me. Always tries to blame me and says its all just in my head but I know he's been different and I just don't understand why. He never wants to cuddle and hardly kisses me or tells me he loves me he hasn't been telling me for like days now. He just doesn't seem to get it. How distant we are drifting apart from each other. And it seems to only be getting worse with time. I don't know what else to do but I try and just not let it bother me but I can't help it. So I'm just confused I feel alone he's not there for me mentally or physically he's not meeting my needs at all. And sometimes I feel like there's maybe nothing there anymore. Like I'm starting to feel different about him. And I feel it has a lot to do bcs there's just nothing there anymore and I mean no romance, we never talk it's almost like we're just roommates he hardly ever wants to be intamate I can't even remember the last time we had sex. And every time we do is bcs I ask for it. Never comes from him. We have been so disconnected with each other and he doesn't see it or seem to care or see anything wrong.  Am I over reacting or what should I do at this point I just feel like I need someone to talk to maybe I am being to needy. But I don't see how if he was always so attentive and would meet all my needs. Isn't that what marriage is? A life long partner and to love & be loved. Am I missing something what do you ladies think?
