Are you not interested in a healthy partnership w/an available woman, Wasabi? Everything you do has fallout. Even if you manage to keep yourself from being shredded in this situation, you might put a future relationship at risk. Personally, I would never take seriously a man who had a history of getting involved with a married woman. I'd have serious concerns about his morals. AND his intellect for getting involved in a mess like this in the first place.
Just saying.
Second thoughts can generally be amended with judicious action; injudicious actions can seldom be recovered with second thoughts.
