About 4 years ago, a girl befriended me and I grew to love her over the year as we hung out more and more.

I finally decided to ask her to be my girlfriend and of course, I got rejected.

I didn't take it very well when she rejected me; I was heartbroken. I cut off all contact with her, including mutual friends. She did try to get me back as a friend several times and I eventually changed my mobile number and deleted my facebook account.

About a year back, a mutual friend of ours found my new facebook account and we re-established the friendship we had. It wasn't fair that I cut him off over a girl and I appreciate that he did look me up.

Recently, he's begun telling me about how the girl was really sad when I cut her off. How she dated other men and got burned. And how she's learnt and matured from those experience; and is now asking about me when they meet up.

He wants me to at least meet her up once more, for closure. I told him I'll agree to it but only on the condition that it's a whole group gathering of our mutual friends.

About a week back, I happened to encounter her as we passed through the same door. She's with another guy but they're not holding hands or anything. I turned (initially not realizing the familiar face), she was smiling and waving elatedly at me. I instinctively did the same before walking away.

I am considering to close her for my own closure, but even so, I'm not sure if I want that.

I think that she's probably trying to find a beta now that she's been burned by alphas.

I appreciate any advice on how to deal with this case.
