The hardest thing about infidelity and abandonment is that it is so cruel and UNFAIR. But that is what it is, and that is hard sh*t to swallow.
Regarding bitterness, I have heard it is deferred mourning.
Do you know, the best revenge is letting OW have them. It really is. See 97% failure rate statistic, above. Inevitable for such selfishness and betrayal, really.
