Not Forever Friends
When you wake up to the reality that not all of your friends and acquaintances were meant to be around forever, then you can emotional move on.

Expect to be friends?
You can not have a friendship with someone who isn’t available for it for what ever reason. And you can’t do enough or buy enough to win them over to seal the deal. Just ask them for the level of friendship you desire and wait for a response, don’t have expectations.
