Can you have sex with (married or long term spouse) if you have lost feelings for them

Little back story. My husband and I is going through it and it could lead to divorce. Recently Sometimes we are good and then we aren't.

He's the one that called for the divorce and said he lost feelings for me. My husband is going through other like (work - military navy) and he's depressed. He gets anger with me a lot and fast. But he still comes on to me for sex. I never come on to him. Told him that I got us a hotel in Vegas for two night and he ignored me and didn't even say he wanted to go. When I wanted to go through his phone or anything he says "he has nothing to prove to me". He can't answer a straight up answer whether he wants to be with me. He always says "idk" or "I can't answer that".

When we are done having sex I feel like a two dolla ho. I am tired of feeling like this he makes for feel low sometimes. And vice versa I have made him feel low (my disrespect and my mouth) so nows he's fed up and basically doing to me what I do to him. But what he's to me I've never done to him. There's a lot more about our situation it's just to much to say in text.
