I, too, was involved in a short but incredibly intense relationship with someone that I am only now coming to believe is bipolar.
Since our split 9 months ago, she has subsequently ended relationships with two of her best friends and moved on to other short term and incredibly unhealthy/tumultuous relationships with other men.
She has made a claim that I am stalking her and that she fears for her life because of me, all entirely unfounded and, though it frightens me to even suggest it...delusional.
Our relationship ramped up very quickly and was incredibly intense, discussions of marriage, children, a life together became common for the time that we were together.
I struggle now, having recently reached a point where I do truly believe she suffers from the disorder, because the people that we were mutually close to, including friends and family, have also been convinced of the unfounded fears she has. So, her friends, family, etc. have bought into her claims that I have stalked her and that she has good reason to be afraid of me.
At this stage, my concern is no longer even about reconciliation, but about her well being and the well being of her two children, who I had grown to love like they were my own kids. She is on a very destructive path, with bad relationships and poor decision making and I am trying to find some way, somehow, to see how she might be able to seek help and treatment. While our relationship was short, I had known her for about 15 years before we became romantically involved. I have seen her at her absolute best and when she is there, she is amazing and wonderful. Much of our relationship was that way was well, but when we began to experience even the slightest "bumps in the road" everything turned dark and FAST and led to our estrangement and many of the same threats (restraining orders, etc.) that LostAngel speaks of.
I, too, am looking for a way to see how I can get her help. I've thoughting of sending her books on BP, just to get her to think about the potential that she may have it, get evaluated and, if properly diagnosed, get treatment. I fear that she will continue on this path, undiagnosed and in turn, ruin the bright future of her life that she could have before her....with or without me in it.
If you or anyone you know has been successful in getting someone to pursue treatment and/or have any stories that started like this but had a happy ending, please share with us.
