Yup. Can't imagine keeping a woman around for the frustration. We keep women around for the purpose of receiving a certain amount of comfort. Sex. Food. Companionship. And sure, we're prepared to deal with a certain level of difficulty. A certain amount of effort from us men is available. But if the scales begin to tip too far toward the frustration thing, then some men quickly wonder why they should continue to tolerate that. I certainly do. My life is good. I'm busy. Good career. Family and friends. Projects. The LAST thing I need is a primary relationship that brings more frustration into my life than it helps me to resolve.

If it's fun, do it. If it stops being fun.......STOP DOING IT!
