I have had to write off many friends and while I got along with a lot of people.. I have only a couple of TRUE friends even though we don't see each other a lot due to distance.. but ones I had to chase down to talk to for 5 minutes I let go of. Even ones that I thought were really good friends.. after almost a year of never hearing from them unless I called them or others not meeting when they said they would.. I had to just let go. Sucks but you have to do what's right for you and not try and please everyone else or be the glue that keeps your friendship together.
