Had she not confessed and I figured it out on my own I would have bolted. Major lies and omissions have no place in a serous relationship and tend to hurt those lied to.
Now not all of us married hobbyists are cheaters. (Same goes with married providers; my wife is no longer cheating even though she beds others.) I do not cheat. My wife approves of every lady I bed before I bed her. It was her idea I do this. If a wife knows, approves, and encourages her husband bedding others is not cheating when her husband does so. Fact is to be honest I am hobbying less and less as the novelty is gone, my favorites are gone, and the sex is better at home. I still see a lady about once a month but I could pass. I have no doubts I could go back to being monogamous, I doubt my wife could.
