conspiracy

Why do I feel like there is some conspiracy against me right now? Every time I set something up with a girl, and they seem excited about it, they mysteriously stop talking to me? Last night, for example, I set up a date with a girl, and then she never contacted me again. And tonight, a girl was going to come over with one of her friends and we were going to hang out and now she has not returned my call or text from yesterday. What is going on here? Either I am just paranoid, or there is someone that is out to destroy me.
