Nights are cold and all we talk about is work & money

So my husband and I been together for 5 years. I don't know what happened but nights are cold now.. and conversations are just about work and money. I do not want to blame it to "marriage". I do not want a sexless marriage but that's kinda what's happening now... For 3 years. I talked to him about it nth time already.. and nothing's changing.. also he likes to watch camgirls.eventhough he knows how I feel about it. I think it's very disrespectful. I don't know why I'm posting this but I got no one to talk to. I'm not happy. But don't get me wrong I love my husband and our children.
