i know
and even i dropped a mate, a really good mate, best mate almost; we played together in a band, we were in the same class when we were 12, we went together to every place where there was something to happen etc
But he changed (of course but not in a way he's grown up) and i stopped our relation, because i felt bad about it, and he didnt want it to see.
And this is not the only thing, he messed around with other mates of me. And some other stories i wont tell.
And I broke up with him. Fair enough. I will say hello to him if I cross him, but things will not be the same anymore.
