I had an emotional affair, and also a friendship that ended after a one night fling while married and both times in a manic state...it wasn't entirely because of the bp, the marriage was already in trouble (it died a very slow death) but I didn't have the inhibition I would have had normally to keep myself from doing any of those things...I was vulnerable to attention because of the troubles and uninhibited by the mania. I don't entirely regret either although ending both affairs caused me to have breakdowns, one of which put me in the hospital. However, the love I was getting was worth it because there was no love at home. it made me realize what exactly I was missing.
