Charlie, I think that you're perfectly entitled to the feelings you have. I spent many a b-day/holiday calling my father cause he wouldn't call me and I remember very well how it felt. There was a time that I had to cut him and the rest of his family off. Now that they know how they made me feel, we are working on our relationships. Like DE said, it's not an easy thing to do, but it just may be the answer that you're looking for. Hope this helps.
