I was reading through some of the back threads and I saw yours in the back stabbers thread. It was clear to me that you really felt hurt by your friend's behavior. I'm sorry you felt so hurt. But I wasn't sure I understood why you were so puzzled by her anger at you. I'm convinced I must be missing something here, because the way you explain it sounds that she might well have expected you to invite her to your party, and that she was right to have been bothered, as a friend, that you didn't.
I'm sure I must be missing something here, but I don't even know where to begin asking where it is. I'm sure that you must be making sense when you're talking about this, but I'm not clear how. I'm certain that it makes sense to you, of course. Have you been able to patch things up between the two of you? I do hope so. Life can be such a yo-yo sometimes.
Best wishes, Bob K.
