Free...get ahold of this friend and ask why ya'll no longer talk...sometimes life events separate people, I know it happens between my friends and I often. My best friend, after she was married recently we lost touched and deep down I think I was bitter. But then, the peacemaker I am, I called her and asked what was going on and why haven't we been in touch. She apologized and then began to make the equal effort. We talk everyday again. Sometimes you have to be the one to patch those ends and ask questions.

Good luck...don't be so hard on yourself...life does this to people.
