So I dunno, this is meant more about friendships but I suppose it can apply to any type of relationship.

At what point does it become ok to abandon someone you consider to be a friend? Is there ever an appropriate time? I guess there are so many situations and other factors to consider that you can't expect a blanket answer on such a question. But at some point I imagine that pushing yourself on someone who doesn't want or appreciate it that your only succeeding in torturing yourself over things that are beyond your control to change. But I mean if you ever really cared how that person was doing how can you ever really let go?

Once in a while you hear of people that have been friends since childhood. And I wonder what makes that bond between them so strong that even after they may have moved miles away, after they had their own families, they still remain in contact even if it's only on occasion.

Maybe they never encountered a situations that challenged their friendship. Honestly that would probably be my bet but there is always a chance that maybe one of them or the other was too stubborn to give up when everyone else thought they were wasting their time.

I dunno, seems kind of stupid in a way. I mean in some sense maybe the person is just being selfish for not letting go when it's obvious they should. If someone doesn't need you they don't need you, at that point anything you do is mostly just for your own benefit.
