I feel so alone

For months now I’ve just been feeling so alone and disconnected. My husband barely even spoke to me today. It’s been like this for a long time. When he walks into the room, he doesn’t even look at me or acknowledge my existence. When I speak to him, he gives me short answers, straight face, and 0 eye contact. After dinner tonight, the baby was crying so I said I was going to take him upstairs for bath time… my husband walks over to me, takes the baby out from my arms and goes upstairs and starts giving him a bath. I waited a few minutes (confused), went up to the bathroom and asked him why he did that? He said, “he was crying and he doesn’t want to be around you”… I don’t know what I’ve done to deserve this. I feel so pushed away. Now, everyone in the house is asleep and I haven’t had a hug, a kiss, or a kind gesture all day… it has been like this for a long time. I feel so alone. I try to be kind, loving, considerate… and I get nothing in return. When I ask him what’s wrong he gives me nothing. I don’t know what to do.
