I'd be shocked if there weren't someone else, LoveHer, but it really doesn't matter -- your course should be the same. LET HER GO, WORK ON YOURSELF, and begin to demonstrate -- over time, consistently -- that you "get it" and are a changed man in regard to her prior marital complaints.
Whether that attracts her back or whether it just better equips you in your next relationship, you need to do those things. As Cadet likes to say around here "your wife has given you a gift of time -- use it wisely."
