HOW OFTEN SHOULD I CONTACT?

talk to her on msn first and text her first!
at least a couple times, and see how she reacts. If I was her, that would be just the push to get me going into the conversation. Just knowing a guy wants to talk to me enough to start the conversation makes me want to talk to him a lot more.

Maybe she's tired of always starting the conversations? and maybe she thinks that you don't care about talking to her as much as she cares about talking to you, so she's trying to stop contacting you as much, thinking that you don't like it.

This is how I'm sort of feeling right now in my relationship, so maybe she's feeling the same way

It doesn't matter if you i.m. her or text her first. Just don't do it so much that it gets annoying. I would get to know her and break the ice. Ask her to hang out like do something you both like or somewhere you can talk to her and get to know her better. Call her and see how she acts. If she is bored and not talking much then she is not interested, but if she says to call anytime and talks then go for it.

well maybe instead of texting/IMing all the timw you should go out. like IM her and say "i haven't seen you in forever!" and maybe jsut start talking and if she seems interested enough in talking to you, then ask her out somewhere. I hate when guys can talk online but can't talk in person. prove to her that you're worth it. Movies aren't good for dates, at least first dates because you can't talk. I love walking or maybe going roller skating/ice skating. that cud be fun because you cud help her up when she falls etc. good luck! :)
