No offense... It sounds like he was being an ignorant a**hole.

There are plenty of BP parents here who've successfully raised children of their own.

Even though I'm BP, I've definitely found love and happiness, although I'm not in a relationship right now (by choice) because my mood has been all over the place recently.

But anyway... If he can't respect you for who you are and doesn't want to understand BP, then your friendship with him isn't worth it (in my opinion).

As far as "why" he would say such a thing... He can't be bothered to educate himself on mental illness. He, like most people, believes stereotypes.

If you still want to be friends with him, tell him how hurtful that was. While you're at it, take the opportunity to educate him on BP. He obviously doesn't understand it
