B and I have been married for ten years and I knew going in that he was BP. He had a hospitalization just 5 months before we got married. I'm not saying I'm some kind of hero, but that noone is without flaw. The BP thing is harder than some, easier than others. One of my friends said once that if B wasn't such a big pussycat that she'd encourage me to move out NOW.
The financial side of BP is hard and hurtful. We have to have constant discussion about need VS want, and soemtimes the bank account is just empty (sigh).
The upside of BP is that the funny and energetic person that you are involved with wouldn't be that funny and energetic without BP. I told B one day to tell his Muse (our nick for being manic) to F&&k off and leave him alone. The only problem is that he is a scientist and without his muse his work is only good, not brilliant.
We've had our times,, god knows we'll have more, but it is very affirming to me that I see some of the things that we've weathered as a couple happening to others and I hope that my experiences may be helpful to some of you who have been doing this for less time than me.
One of the hardest things that I have had to do since I found out is to stop overanalyzing behavior. Sounds trite, but sometimes happy is just happy, horny is just horny, and sad is just sad. Talk to me in 6 months and things might be bad or good, doesn't matter, we married for better and for worse and as long as the bank card stays in my pocket...
