Omg. I'm not the only person who "went polyamorous" when manic? What a relief. Somehow this makes me feel so much better. You sound like my twin! I even wrote up a careful list of tenets, "Terms for Polyamorous Peace." Only problem was that I immediately started breaking those rules, but didn't care. My poor husband. No one could convince me I was being irrational, hurtful, and dishonest. It wasn't until literally a few days ago that I realized the guy I was in with--whom both my husband and I knew--was a narcissist and that he was truly enjoying how much the relationship he and I were in was torturing my husband.

That part of the whole mania--hurting my husband--is the worst thing I've ever done. Not the polyamorous part. I think polyamory is fine if done right.
