Some men will never understand

My SO has always been the one to understand me and be there for me, but as of late he's never there. I'm 33 weeks pregnant as of today and it feels like things have changed over time. Before we found out I was pregnant I understood that he had his own things to do but it's like it's so hard for me to do things alone now that I need him around more often and I need his help. He's been neglecting me and my feelings. And another problem is that his family is constantly calling him and needing him and within a blink of an eye, he's always there for them. But when I need him he's no where to be found. Even for little simple things like spending time with me, he can't even do it. I understand he can't do it everyday but to have him tell me everyday that he's too tired or too busy breaks my heart. Our little guy isn't even here yet and he's barely home already. It makes me sad that he doesn't want to do anything with me anymore. I've written on here before on what I could do to let him know, and most ladies said to talk to him and really let him know how I feel. I have a few times and it always left me crying in our bedroom alone. The last time we had a talk, all he did was look at me like he didn't have anything to say or that he didn't care. I don't know what to do with him anymore. I don't know what to say or do that'll make him understand that I need him more than ever now. Especially since his family doesn't like the fact that I'm pregnant and that some of his other aunts and uncles have been talking shit about me. He doesn't understand how hurt I am. How alone I feel. I feel so lost and heart broken.
