Just to update everyone who has read and commented:

I spoke to this girl on msn and said, i don't think our friendship is working.

She asked a few questions, and i told her that she had annoyed me a lot.

And then she said, this is stupid it's not like it's going to do anything cos we never do anything anyway.

OMG! Wouldn't she say something like, if you feel that way, that i've neglected you, let's catch up then.

It's obvious i'm not important to her.

So i came away feeling really satisfied that i'd done something good for me!
