IMO, the best revenge per say, is when he is old and needs someone to wipe his, umm yeah you get the picture...show him that unconditional love does exist, that you will be there, even when he was not. A late lesson in life, yes, but one that may bring you both more closure and comfort than you know. To walk away from him at his time of need, is proving his point, that unconditional love isn't real. But to give him the help and love he needs then, proves IT DOES.
Very wise words.
You're a good friend, sweetstuff.
Looking-glass,
What does one say to a post like that?
LOL!
