It looks like I am one of the few girlfriends who decided not to stand by my bf when the BPD became too much for me. I struggled with my decision, but ultimately I think I did the right thing for me. However, there are times when I feel unbelievably selfish for leaving him. When we first met, he was in a hypomanic stage, although I wasn't aware of it at the time. I thought that he was just a very positive, outgoing, energetic, impulsive, interesting person, and our relationship moved really quickly. He said he wanted to marry me and have kids, live happily ever after. He spent money recklessly and we went on trips. It made me nervous how easily he spent his money, but since we just got together, I didn't think it was my place to tell him how to manage his finances. Looking back on the situation, I recognize the symptoms of hypomania--sleeping very little, talking a mile a minute (so many ideas!), grandiose visions of himself and his future, reckless spending, excess energy, etc. Now, six months later, he is in the throes of depression. The few friends he had when we met have drifted away. He hides out constantly in his apartment, zoning out in front of the TV. It didn't matter how hard I tried to be cheery and lift the mood, it seemed like there was a cloud of depression settling over both of us. He would get this dead look in his eyes, and I would wonder where all the life in him had gone. He would be needy, and no matter how much love I showed to him, it wasn't enough. Because I know that he wants to get married and start a family(regardless of the hypomania or depression), I had to ask myself a question...is this life something I can commit to? Is this the life and the struggle that I choose? The answer was no. I feel terrible about "abandoning" him, but I kind of felt like I had to jump ship. I had no idea what I was getting myself into, and the more I've read on BPD, the more scared I became. He is now seeing a psychotherapist and considering meds. I hope that he finds ways to cope to have a successful relationship in the future. I also hope that I'm able to deal with my own feelings of guilt. What he needs now is support, and I know that--but when I met that wonderful, dynamic guy, I had no idea that so many of the qualities I loved about him would slowly disappear until he changed into a completely different person...someone who is closed, withdrawn, socially awkward, sad. Am I obligated to be there no matter what in a relationship of only 6 months?
