<human>: Condense the text into a few key points

I know this girl since high-school and we always had some affection for each other. We kissed once in high school and we had sex a 3 to 4 years ago later but then we carried on with our lives and didn't speak again.

Last year we started to talk again and she seemed to be giving me signals that she was into me and since I was single, why not? We used to chat everyday and I even took her to a concert... later I found out that she had a boyfriend but I figured they would break up soon.

Meanwhile I started dating another girl who became my girlfriend, so I started to change the tone and contents of the conversations with my friend but as soon as I told her out our history and she made me cut ties with her. There was no closure, I just stopped talking to her at once and she became desperate, sent me countless messages, mails, removed me from facebook then added me again, etc, etc. but after a few months it stopped.

We broke up recently and I miss talking to her. She still has her boyfriend but I'm not even thinking about having anything with her, I just miss her company. I've been thinking about talking to her but I don't want to tell her exactly why I stopped talking to her.

What do you think?
