Well, sometimes I have trouble reading posts on the internet... it's like I keep missing some words here and there and the posts never make any sense... so if I'm misinterpreting your posts let me know... from what you've written, it looks to me like she is not interested in anything but being friends and the noncommunication may be her way of trying to let you know, although if that's what it is... it's a really bad way to do things in my opinion.
She should at least reply to your emails to give you a definitive answer as to your relationship with her.
I could very well be wrong Tim... I wish I knew more but I'm not going to know as much as you can know about all this.
If you communicate to her your feelings and she does not answer but is online elsewhere, I really get the sense that she is avoiding the situation for some reason.
It could be so she has time to think about things, give you time to cool your heels, or just flat-out ignoring your emails hoping you'll quit sending them.
If it weren't for the myspace thing, I'd say she might just be forgetting to reply or is taking her time in composing a reply.
Anyway, I hope you don't let all this play around in your mind too much. You know, I'm sure, that you can go on imagining all sorts of scenarios that will most likely depress you. Keep control of your imagination until you know something solid from her.
