Dude, did you really think she'd break up with her boyfriend to date a guy she broke up with a year ago? She moved on. Honestly, I think you should too.
So what if she calls you for support? That doesn't mean she'll get back together with you. I completely agree with cmacattack1. I've noticed from experience that girls tend to use guys for emotional support pillars way too often, and usually out of selfishness they rely on the people interested in them knowing they'll get their biggest ego boosts there and pretend like they don't know this gives the guy hope. Ugh. Sorry, I've seen it happen and had it happen to me too many times. Very annoying.
