Welcome to PC and the bipolar thread mumamoose6. Bipolar does effect our relationships, but if someone REALLY loves you they will go through it with you. I couldn't imagine doing the dating scene again especially being bipolar. It is hard to open up about the illness with someone you know and love, I wouldn't know how to cope with telling a potential spouse. The good thing about being bp in a relationship you get a better idea how much someone loves you because it is hard for them as well. A letter does sound like a good start and I hope he will be forgiving, but if he ain't, as much as it may hurt, how can he be the one if it is not willing? A new diagnosis brings a lot of mixed emotions so take this time to educate yourself as well.
