I agree with coralproper....you got to do stuff that you like and then you meet more interesting people and then these group of people want to be with you...then it's your choice to accept them as a friend or not!
This has happened to me before, and then when they saw me happy going on my own life and having very good friends around me, they tried their best to get back to me...but I didn't....
These are not true friends...true friends won't do such a thing!
take care of yourself
