Im utterly confused

Okay so the low down is me and ths girl dated while I was in high school one of our mutal late friends introduced us, we dated for about a year till she broke up with me. She broke up with me because she felt like I was going to hurt her or break her heart , but could never tell me why she thought that way , I had never cheated on her or treated her bad... We started talking on and off a few months later , then she broke it off again. After she broke it off , one of my old lady friends came down and well me and her had sex. So when my ex decided to talk to me again it was going good , but she had asked if I had done anything while she was talking to some other dude, I wanted to tell her no but I told her the truth.. We quit talking for a few months again , then she invited me to go see her , she all excited , etc.. I decide to break it off this time , and after I did she got a boyfriend, they have been dating almost a year. During this time I got a girlfriend too , and maybe 2-3days after I break up with this girl she decides to add me on facebook after I deleted her a year ago. Now I still have feelings for this girl, I know shes keeping tabs on me because thats how she is , but what should I do , why would she want to keep tabs on me????

Coz she has never forgotten you, or maybe she still love you.

ah the confusing love life of a college teen , my current girlfriend keeps telling me I "deserve better" which I think is her subtly trying to get me to break up with her , and deep down I think I still having feelings for an ex from a long time ago....

If you like the drama, keep contact with her.

If not, break it off entirely.

eh well I haven't talked to her that much recently , but its been drama free for awhile now but also alot less contact
