Similar thing happened to me few months ago. I fell intensely for an intense guy. He dropped the bomb he wants to date a younger girl. He was a jerk and I'm the bipolar one. I thought maybe I was naive or suckered in because of my bp. But now I think nope that's just how fast infatuations make anyone fall & a crush because someone gets hurt. Best bet might be a slow & steady builds a strong lasting relationship.
