Classy, I'm sorry to hear about you being hurt. The answer to this question for me is yes. As I posted in another thread, it looks like I am headed for another estrangement with my father, this time for good. We have been talking for a year, after one of our long estrangements, nearly two years last time. This week he has conducted himself in a manner, which shows that he doesnt seem to care, if we are estranged for the rest of his life. Last year, after I reconnected with him, he sent me a lying e-mail saying he wanted a "new beginning". Well, he has spent this year acting even more hateful to me than he had in the past. In recent days, I have been unable to sleep. I think about him, us, and our relationship, many hours a day, and it just makes me feel so devastated, and disgusted that he acted like this again.
As others advised you in this thread, I myself have been advised to work through the anger, and try to forget about my dad. In cases like yours, and the one I have, I think there are stages of emotion, such as sadness, anger, resolution, and acceptance. Eventually, the acceptance emotion does take over. Hopefully, in time, while your feelings might never totally go away, it will reach a point of acceptance where it just gets easier. This happened to me at points with my father, when at times we were estranged for as much as nearly 3 years at a time. Hopefully, in time, your emotions will begin to reach such a point, too. Good Luck.
