should i let her back in?

Hey,
sorry for the long post!!
since this is a relationship advice question there's obviously a lot of backstory that would take too long to bring up on this (unless asked for) so just gonna keep it quick & to the main points.
I was going out with a girl for a year or so, been broken up the same amount now and she's trying to get in touch with me. It was a pretty much perfect relationship, both on the same wave with everything, things couldn't have been better, felt like real love-for awhile anyway.
The break up though was over her cheating on me, only went as far as kissing but it was 3 times with 3 different people, one was a guy where they used each other for sex when single and he always would try it on with her if she was single or not, another was a girl, my ex who simply put would do anything she could to ruin anything that had me happy.
There was a month or so afterwards of being upset alot, for both of us, over what could've & should've been. After this time i still wanted to reconcile but she was along the lines of 'one day' so i decided to cut ties to start getting over it & her. Every so often i would get an IM from her or a txt just sayin hey or how are you-general chit chat openings that i never replied to. But they became more frequent and she seems interested in meeting up to talk, about what i don't exactly know, i assume to be friends or maybe more or to even just clear her conscience.
Any ideas what she's up to-or suggestions of what to do next because i am stuck! Good bit of confusion is because i don't know what i want out of it exactly.
Any ideas?

If she doesn't make you happy.. the answer should be obvious.

If she's given you no indication that things will be different, you should steer clear.
