I can't add much to what has been said before except that we all go through these blips. Obviously only you can eventually decide what you want to do, but I think you should exhaust all the possibilities before you make a decision. You sound fed up so... Don't have an affair !! You are right men don't listen, but you need to open him up somehow to improve the situation, only you know which buttons to press, but as said before take him out for a meal, surprise him and then start talking, not a full blown psychological profile just talk...try and remember the early days, the things that make you laugh. I also think he might have some issues, not many men go off sex there usually is a reason, maybe he is fed up also. Introduce him to your vibrator !! Don't assume he knows what you are thinking or feeling, in my experience they haven't a clue. Good luck, keep posting hopefully it helps.
