I don't know

[dchase]

A bit of history before I get to my problem.

So this was my first girlfriend, we had been together about a year when she cheated on me while on another island, and then told me about a month and a half later, when she broke up with me because she said she felt too guilty. A month later she says she misses me and wants to get back together, so after mulling it over a few days I accept, mostly because I still loved her and thought I could forgive her; and things are sort of back to normal, but I don't even mention what she did for fear of her crying and such, even though the only detail that I know is that she cheated in some fashion. Anyways, things were going pretty good for about 4 months, and she started getting distant, everything physical just sort of dropped out of the relationship, and admittedly there wasn't that much talking at all after we got back together, or before she cheated in the first place. So after she starts getting distant she says that she wants to "take a break," which I go along with for a few days, but then she comes to me crying after I've made sure to have absolutely no contact with her throughout the break, and has me comfort her as her friend about her boyfriend troubles, needless to say this wasn't very comfortable for me, and I finally decide to break things off with her. This was about three months ago, but I still really miss her. I think that I did the right thing in breaking up with her, but she still wants to be friends(or so she says), even though she doesn't seem to be putting very much effort into it(we've talked for a possible grand total of 15 minutes since the breakup). I'm not really sure what sort of advice that I'm looking for, possibly just anything to help me get over her, or to figure out what I did wrong so that I don't repeat it in the future.
