very glad to hear that things are more positive for you!
Friends who were friends before you "came out" as poly can be a tough issue. Most of them don't "get it", and, to be honest, they probably never will if they are "wired for mono". I have had to learn to accept that and make some new friends through our local poly groups that I can be more open with and who understand.
