I'm with polyexplorer on this one. I fell in love with my married neighbor (and his wife and I were friends). Do I feel guilty about our affair? Not one bit. She was horrible to him. I saw it first hand. The way I see it? I did her a FAVOR. She has tried to turn around and blame it all on me -- interesting, as she is with someone new and appears to be very happy with him...
Anyway, true -- it's not black and white. Follow your own conscience.
Formerly married to Sundance
Boyfriend -- Butch Cassidy
