I don't think it's "impossible" to come back because she thinks I won't forgive her.
(She has admitted, however, that her involvement with the OM went beyond a certain point so as to "burn her bridges" with me.)
Her stated reason (or at least one of them) for why she "can't find her way back" is that the OM is "soft" and "gentle" with her new self-discovery. He must appear as a little angel of personal growth.
I appear, on the other hand, as a watchful Jehova-jealous figure, who casts a mean glance on whatever I don't like about her.
(I'm getting lumped in with her father her. But keep in mind the whole tattoo thing, which is indicative of our dynamic: I don't think it's a great idea to get tatooed with anything, my name or otherwise, and I've said so in the past. So... I'm not "supportive" of her "growth.")
If it weren't for the adultery going on under my nose, I might find it a lot easier to be "accepting." In any case, I would keep my comments to myself unless asked.
(I'll admit that I'm an opinionated SOB. It would be hard to become a new-age flower child overnight, and I have no desire to be anyone other than who i "am".)
