I understand. I've been on both sides of this kind of situation. I understood perfectly.

My point is that simply disappearing from the lives of other people without telling them is childish. We've all done it though. That doesn't make it right, appropriate, etc. I can see both sides of the situation based on what you posted. You don't have to be friends with anyone who isn't meeting your needs or reciprocating appropriately. It's just better to tell a person where they stand in your life. Be strong and be ready for the reaction.
