I agree with wiretwister. When you find the right person, it just works. I'm not saying it won't sometimes be hard, but you will work it out. In fact, our family motto is "we will make it work". And it applies to more than just relationships. My side mirror on my car is currently held on with electrical tape.
My husband and I just celebrated our 4 year anniversary. He's been willing to stick through all of this with me mostly unmedicated.
I admit that sometimes in in the past it's been hard for me to tell the difference between my feelings and feelings that I am experiencing solely because of the Bipolar Disorder.
