Anyone have any crazy ex girlfriend stories?

I was 16 when I lost my virginity. A couple weeks later, she told me she was pregnant, even though I wore a condom lubricated with Nonoxynol-9 (spermicide) and she was on birth control. I was skeptical until she showed me a positive pregnancy test. Still somewhat skeptical, I asked her to take another test, which I bought, and gave to her as she went into the bathroom. When she comes out, she's holding a pregnancy test that was positive. Only that's not the one I gave her... I go into the bathroom and underneath the trash bag lining the trash can, she had hidden the test I gave her. She had a pregnant friend of hers pee on multiple pregnancy tests in case I asked her to take another one.

Went to her house to get my things a few days later, and I walk into her bedroom. I can hear her crying, but I can't see her. I look on the other side of the bed and she's sitting there holding a serrated steak knife with 3 or 4 fairly deep, bloody slashes into her forearm. Crying and yelling "you did this to me !" I did not do that to her - she's a liar. So I left. I'm 29 and I still use condoms even when I'm in a relationship. Just cause you never know...
