I wasted my time

I'm not angry that you don't care to spend time with me, seeing that we were friends for 19-21 years. I'm angry that I wasted my time with a self absorbed person that can't even acknowledge that her friend was and still is hurting inside... The fact that when ever I try to express myself you always have to be right and can't just listen to what the other person is feeling. That's not what friends do.
