No, it isn't. This is just what people say when they are trying to extract a relationship from dysfunction.
You are making poor choices here. You know this. This man isn't interested in your feelings and tending to your emotional needs. He's just after sex, and it sounds as though he isn't very interested in the sex anymore either. Either he's getting it somewhere else (and I mean, from someone other than you or his wife) or he just isn't feeling it anymore with you.
Either way, this is going nowehere and it's no longer serving you. It's up to you how long you want to prolong your own misery.
