Illogical?

So, what kind of a crush is this (for a crush is surely what it is) it is something that deserves at least a little bit of thought, after all its been nearly five years (I think) without even feeling the need to so much as look at another girl.

Its an odd one, in that i'm quite happy with what i've got, although a little bit more stability would always be appreciated (if only for her sake).

Obviously its a little bit painful to see her going through the difficulties of relationships (especially with those who don't get her, or actively seem to be taking advantage - although of course I'm going to have a fairly universally dim view of them) but a little bit of heartbreak is not so great a price to pay.

The problem of course is that I just don't have the first clue what she really thinks of me. Its always possible that i'm a real pain. Still she knows all this and you think she'd of said *something* by now if that was the case.
