If you regret this, then you should not date. Really.

You have to enjoy dating for the ride, both figuratively and literally in this case.

99% of all the first dates you go on will end in eventual "failure." It's part of the deal.

It's not about there being anything wrong with you or evil about them or whatever... it's just the way it is.

And, you're right-- you aren't going to see her again, and that's also just part of dating.
