I understand the pain of past friendships that have really let you down.
I don't handle the disappointment very well. I keep trying to figure out what I did wrong, 'cause I know it's somehow always MY fault. I can't stand it when "friends" dispose of you without a word of why or goodbye. They just lose touch. I get mad about that. You could at least yell at me about something or you know, call me an idiot-don't just fall off the face of the earth.
Anyway, that's how I handle disappointment in a friend.
