Why make friends?

In my poor experience, there are only 3 types of friends. Friends with whom you communicate for a long time, for years without any reason to stop communicating. Friends with whom communication ends in a week, when there is no attachment yet. And friends with whom communication ends in about a year.

It's clear that this is a problem with my social skills. But from these same people (friends of type 3) I hear that this is normal, this is how any friendship goes.

If this is so, then in order not to suffer for a long time after the end of the friendship, you first need to experience many such friendships. And if not, then the problem is in me and excessive attachment.

I want to ask where I'm wrong, because obviously I am wrong somewhere. Or am I just that bad at making friends?
