I have never experienced this in my relationships. Looking back at them, the guys I dated were pretty normal. I was the messed up one being undiagnosed at the time. I was one whacked out female at times!!! But the more I think about it, the I realize they were generally guys that took advantages of me in many situations. So, they may not have been bipolar but may have noticed that I was and decided I was easy pray. Good thing they are all ex's!!!
