I've been married to my wife for 10 years. We have a child and we both have pretty decent jobs (not that it's really relivent!) I cheated when we first got together. She has recently (last 18 months) sex is once a week lights off same old. She never seems to be happy but says it's just the way she is. She hates contact and affection but I love it. I feel pretty lonely most of the time and she says she still wants to be with me. But although I love her, I feel we are still together for the wrong reasons. I think we could both be happier elsewhere but it breaks my heart to think of another man bringing up my child. What should I do? Is it finished?
