Why won't my wife sleep with me?

You really need to talk to your wife about this. Not having in a marriage is not a good sign. She could be cheating, but then that is why you need to talk to her. You need to let her know how you feel. It is never good to have this in a marriage. This is why a lot of people start cheating in a marriage because of lack of attention, , stimulation, etc. You two just really need to sit down and have a serious talk, maybe even get a marriage counselor. I really hope that things turn around for you. is a huge thing in marriages, never undermine it. It is what brings the two of you together emotionally and physically. A good life in marriage is healthy, a bad one...not so healthy. So yes, just talk to her and hopefully you guys can see what is happening between the two of you.
