I've had three girlfriends, one of them stalked me, another one I asked out and she was my girlfriend for a while, then we broke up. One year later, she stalked me too and her friends tried to make me ask her out. The last one I asked out and we were together, then we broke up. My problem was solved.
What you should probably do is go out with each one of them and find out who you like, and just break up with the others. Might get rid of those stalkers and get you laid.
Mhm.
