She messages me all the time, it's getting obsessive, what to do?

[Frustrated Fran]

That is a frustrating situation. I can totally sympathize that technology has made it incredibly hard to just distance yourself sometimes. Since you don't like her all you can do is be honest and tell her you are only interested in her as a friend. Then tell her that sometimes you really don't want to talk everyday. It's hard to be that straightforward, but I've learned it's the best way. Being polite doesn't always end well in matters like this. Be honest with her about how you feel. And it is creepy she's so jealous...she's just a friend and not a friend your interested in either. Good luck.
