Normal to not talk to partner?

So I’m not sure if my life is even normal. It doesn’t seem like my kinda normal so let me explain.

I’ve been with my boyfriend for 3.5 years now. We have a 2.5 yr old child who’s autistic so I stay home take him to school, therapy, ect. I know my life is a bit different than that of neurotypical children. Anyways. My son’s dad works a seasonal job and he’s not laid off yet. However, this dude doesn’t really talk or communicate with me. He comes home from work and gets on his game. He doesn’t spend any time with his son at all. Our son loves his dad don’t get me wrong. I mean is it normal to be home and my boyfriend in his room for hours, I’m talking 6 pm till 12 am. Then he wants to come hang out and want sex which I don’t. He doesn’t want an emotional relationship at all. Just physical. And to be honest, I’d rather an emotional relationship over sex. Which sounds crazy but it’s something I desire and want.

My son’s dad doesn’t want to break up because he claims he owns me because I popped out his baby. It’s just crazy and I wish this nightmare would be over soon.

I have a strong desire to move out but it’s starting to seem more and more impossible.

Also he refuses to pay child support too so I’m really just not sure how I can do all this. Yes I’m doing it now myself but I don’t have to fend for a roof over my head at the moment. Idk what to do.
