The first that came to mind is set when I was 16. I had just gone to college (senior high school for the American) in a city called Ipswich, best known for a serial murderer and football crimes (I grew up in the countryside) and so I was a blue and dewy eyed innocent. My cousin introduces me to a nice girl and we all hang out. I still date like a country boy, so handholding and kissing and I had only had one partner in my life at that point.

We walk around and she blushes when she holds my hand, but utterly refuses anymore more. Not a kiss nor a hug. We all go to McDonalds together (let me tell you this, when you live 40 miles away from any fast food, McDonald's is a treat) and her friends all go into the bathroom together while we hung out. She then makes out with me hugely for about 20 seconds and then runs into the bathroom. I am left blinking and dazed. She denies it ever happens, and I innocently assumed that it must be because of some kind of female thing and I just couldn't understand.

Later, I am invited to her house. When I try to introduce myself to her mother (who sat obesely staring blank eyed into Jeremy Kyle), she told me not to bother talking to her mother. She dragged me upstairs past a very poorly maintained house (I grew up in a poor family as well, but we were always a clean house) and made out with me aggressively again.

As it began to get heavy, she pushed me away, hid into the corner and started crying. If I came closer, she screamed. If I tried to leave, she screamed. She then pulled out a switchblade and began to threaten herself and I had to try to talk her insane self down. She then made out with me. She then screamed again. She then started cutting herself, and I had to grab the knife. Women, huh?

Later that week, she followed me onto my bus home. I didn't complain, because I was still in that innocent "I can save her" young mindset that the media drills into men. She comes over, we play some video games, I cook her food (thankfully my mother was elsewhere that day), and all seems well. I ask if she wants to go home, she declines. Okay, thinks I.

We end up having sex (yeah, I know, but I was young and horny and stupid) and she starts crying, but if I try to stop, she screams at me to continue. We finish, and then she pulls out that knife again, this time going for me. I manage to get the knife off her, and then in an act of bravery or stupidity I cannot understand today, went to sleep with her. The next day, she woke up, politely greeted my mother good morning, and I took her to the bus back.

However, by this point, even I had come to understand the insanity of what I was dating, and I said that I don't think we can see each other anymore. I told my cousin and my friend who both knew her, and they kinda shrugged "Oh yeah, she says she has multiple personalities, but she liked you so we set you up".

Thanks, girls. I spent three years gingerly avoiding her, except for a one night stand later before we both went to uni on the advice of one of our mutual friends. She was a lot more stable this time.
