Theoden has given you excellent advice. I agree with ALL of it. I have been studying affairs for over 8 years, and have witnessed thousands of them and counseled hundreds on this forum. I have personally counseled over a dozen betrayed spouses, and I also saved my own marriage 7 years ago. Doing what theoden is recommending is not guaranteed to work, but I can tell you with 100% certainty that it gives you the best CHANCE of success, and that doing what you're doing (trying to "nice" him and "sex" him back into the marriage will NOT work!
I sense that English is not your first language? Is there something very male chauvinistic in the culture in which you were raised perhaps?
