Yeeeeeah, I'm not quite understanding what exactly it is about depression that made those guys bad BFs either...

I mean I know there are challenges, certainly, my BF suffers from horrid isolating depressions (and I'm Bipolar) so I'm not in the dark concerning where difficulties may occur, but I doubt his depression could ever be the cause of a break up.

Wait scratch that, I know it wouldn't cause a break up.

Ps. On the flipside, I've had 1 other serious bf who was without depression (or any MH dx) and he ended up beating the shyt out of me. So "normal" can lead you somewhere even uglier than someone with a MH dx.
