Feeling alone during pregnancy??

I’m 29 weeks pregnant and never felt so alone. My fiancé has been giving me less and less attention and i’m so frustrated. He comes home from work I make dinner as soon as he’s done eating he doesn’t even sit there talking to me or help with dishes or ask if i need a hand, he goes in the room to lay down and watch youtube. He also been going to bed super early so I feel like I get no time with him. I only really get time when I take him to work in the morning and that’s cause he doesn’t have his license yet. ( Hes almost 26 ) and I feel like now is the time he should be even more closer to me. I try talking to him bout it, it’s always a argument. I feel like I should just accept the fact he doesn’t want to spend time with me and i’ll ask him to stay up and spend time with me and he’ll be like “i’m tired” and go to bed. He has had the same job for years and this has been recent. Also on his off days. What would you do? I feel like when the baby comes it will just be worse and he’ll never spend time with us. Advice please.. I’m starting to feel like it’s because i’m becoming ‘unattractive’ from gaining so much weight. Its like i’m in this pregnancy alone.
