trust me mate, if she really had bipolar you would know about it. ive had two experiences with girlfriends with bipolar/depression and its not a minor issue. my best mate tried to kill himself a few months ago because his girlfriend who had bipolar was fucking with his head that much. and he is like, the most laid back and rational guy you will ever meet
my ex also had sever depression and the symptoms of bipolar, and she put me through the most fucked up situations ive ever had to experience. its not just being moody, every (and bloke) is like that
bipolar is very, very bad
