Thanks for replies!
Well, I guess I found out that my mistake was that I unconciously continued to keep the links with those people. It's like a habit: to talk to, to phone, to meet them, which actually doesn't bring any use for me. So when it came on my mind, I decided to stop to communicate for a while. My plan was that a lack of communication would motivate me to find other people, relationships, links.
And it works. I feel like every second I'm looking for a new acquitance and I'm ready to start a dialog even with a stranger that brings some kind of confiden to me.
