Hey piglet, glad to help. I know it helps me too to read about similar situations and what was said and done.
Zilla (BFLD!), you may be on to something here:
"That while he may have gotten a huge ego boost from her, it was quickly eradicated by his guilt and confusion and sense of lost self.
Thinking along these lines, the way he was so disgusted with himself and with her, I wonder if his feelings last year of being "in love" with her were simply his way of easing his guilt. After all, his behavior - if not validated by love - is despicable. But, if it was "true love," perhaps he felt he could better live with himself. He could claim to have been swept away by his soul mate and that there was nothing he could have done to stop it."
