Friends only or maybe she is just to busy... I sorta get the hint that you got feelnigs for her or you've become kinda attached... Since things aren't "normal" anymore your just worried she's fading away.... But since she is still replying and messaging back to you means she wants to keep the friendship... Well thats my two cents I'm not her =]
She might like you at 1st, but you didn't do shit (because you just wanted to be friends), so she thinks it's wasting her time
Humans get bored of anything, just take this for an example.. Playing the game for a few months will get you bored. Put it to a point that maybe her hp bill is expensive for that particular time or she does not have time to entertain you.
