I like Lynn P.'s suggestion. I would definitely start there. If that doesn't do the trick and a lot of time passes it might be time to move on and make some new friends. I'm BP and lost a lot of friends in the process and some of these were friends I'd known for years. It was very hard for me to move on but too many things happened and I didn't feel safe or trusting anymore as they had also stayed friends with my ex-husband. I have a few close friends that are my friends and they don't associate with my ex and I'm making some new friends at a Bipolar support group. Whatever happens you will make it through it. I only hope for the best and that you can mend the friendship.
