I feel that way about a former friend. He was cool until he started 'stealing' my friends. At one point I had a really close best friend and I realized he was avoiding me to hang out with that trash

Then after two years, I found another best friend, and that trash took him away too
I know he hates me and I hate him. Pathetic. Every time we get into an argument I remind him of how he used to be a loner with no friends until I invited him to hang out w/ us. Should've never done that.
