Bipolar or not, some people are just jerks. Your ex sounds like a jerk, nothing you posted sounded like classic bipolar mania. Sure I know of some people who've had whirl wind romances, but that happens with non bp folk too, soo, when based strictly on that, I just don't see this being a bipolar thing, unless there are other pertinent factors regarding his behaviour you haven't mentioned.

Let me take the time to set the record straight though. Bp doesn't cause you to love fast, hard yet shortlived.

Even bipolar love lasts, atleast real love does. What you described is classic infatuation, love doesn't disappear over night.

I'm sorry you were treated so badly, and I know its really rough that you can't find closure.

I'm bipolar btw, and its not a free pass to treat my bf like shyt. I've loved him loooong before we even dated. In fact I've loved him since I was 15, and 15 years later I still love him all the same.
