You don't want one, trust me. Dated one for a while, she broke my heart because I'm just a pathetic nerd on a comic site and wasn't what she was looking for and fucked my best friend.
We stayed friends until she ran off to the next town, and even then called each other fairly often. She was my best friend, despite everything, and the only person to really ever help me overcome my social anxiety and shit, but she snapped one day and dropped literally everyone from her life in an attempt to get away from her family entirely. I got over her romantically a long time ago, but I'll be damned if my best friend just tossing me out like a used tissue didn't break my heart all over again.
TL;DR though, she was fucking crazy. Manic in a lot of different senses, and you really don't want a girl like that, anon. I'm actually really grateful us dating never went anywhere because regardless of everything it wouldn't have turned out well at all.
