Found out about 5 months ago that my wife of 18 years was cheating on me. We have been trying to work through it, but it's going no where. I think I could possibly forgive her, but she's not interested in me. She wants to be (because I made good cash, she's jobless with no education, and we have 3 kids together) but says she can't regain feelings for me. It really hurts, but I'm starting to come to terms with it. Started looking for a place to move to (since she refuses to leave) until we either work it out or get divorced. I'm 43, 5' 9", 160 lbs, in good shape, masters degree, good job, like to party, very handy (built a huge deck on my house, installed a fireplace, finished my basement, used to be a roofer), and seem to get along well with most people. But I still have a problem with self confidence (mainly because I'm not satisfied with my appearance), and so looking for something to help me feel more interesting. My other issue is that I needed shoulder surgery 4 months ago and found out I have severe arthritis in my shoulder and will probably need a full shoulder replacement in the next 5 years. That puts a huge damper on my workout routine (I was hitting the weights pretty hard until I hurt my shoulder). Does anyone have any suggestions for hobbies that I might want to pursue to help raise my self esteem and make me more interesting to women?

Thx!
