Cooking breakfast one morning, reached for a knife to chop up the potato, and the whole knife block is empty... looked in the sink, nothing there. Looked in the dishwasher [shudder], nothing.
GF gets up. I ask her what happened to the knives. She breaks down sobbing and says she woke up in the middle of the night, terrified that she would go sleepwalking and stab me to death in my sleep. (she had zero history of sleepwalking, btw. It was just typical OCD ideation). So anyway, she had got up from bed and gone to the kitchen, taken all the knives, and "hid" them on top of the fridge.
Which is crazy. But the most worrying part: when she got up in the middle of the night, gripped by the idea she was going to stab me to death.. she must have pulled the first knife from the block and stood in the kitchen holding it.... for how long?
How long did she stand in the kitchen, knife in hand, while I slept?
I didn't break up with her for that, though.
And I didn't break up with her when she threatened suicide if I wouldn't quit my job to spend more time with her.
And I didn't break up with her for all the times she broke down into hysterical tears because I seemed tired or distracted or didn't seem to be having a good time.
Honestly, I broke up with her because I didn't like being with her very much. It's hard to like a person like that, when you have to police your behavior every moment, fearing she will fall into pieces if you do the slightest thing wrong.
The night I finally broke up with her, she demanded I drive her to a pharmacy because she'd stopped taking birth control in an attempt to snare me into marriage via pregnancy, and now she needed the "day after" pill.
She wasn't a bad person. I still miss her sometimes. But she was really, really crazy. Just impossible to live with. I can't say I'm happier now. But it's nice, not be walking on eggshells all the time.
