Manipulation is not part of bipolar. Sorry, but it really bothers me when people blame what is just bad behavior on BP, it misinforms people who read it and don't realize. We've got enough stigma to deal with as it is.

That said, I'm glad you are taking it to heart and wanting to stop. The only advice I can think of is to try to catch yourself and remember that that is not how you want to be. And maybe learning some healthy techniques for conflict.

Good luck!
