Probability of your 'soul mate'

I'm so depressed ever since she left to college and forgot me. She was the first girl to ever love Hitch Hiker's Guide to the Galaxy and enjoy Invader Zim and tolerate my mathematical ramblings. What do you think the odds are that I'll ever meet a girl like her again? How many women like Hitch Hiker's Guide to the Galaxy and Zim Invader and Calculus?
