Bipolar Disorder Support Group
Bipolar disorder is not just a single disorder, but a category of mood disorders marked by periods of abnormally high energy and euphoria, often accompanied by bouts of clinical depression. This is the place to talk about your experience with bipolar disorder, learn from others' experiences, and find support.
If you are feeling this, then I think you should communicate them to her and see what she has to say. Sit down and talk, tell her if she wants you to back off then you'll back off, but still want to be friends.
I know this will be hard for you, but it's better than losing her. Maybe the guy just doesn't want her around you because you're an ex. It could be anything.
I think you should probably be on the lookout for some new friends to hang out with just so you have them around for things to do with and keep you company.
I don't think it's the bipolar that is bothering her. If she is a true friend then she won't have a problem with talking to you about it. The key is communication in any relationship. I wish you the best of luck and hope she understands how you feel. Hugs
