Here is the story:
On Saturday this girl from Brooklyn in New York took a fancy to me and started to call me baby and all that. On Sunday she spent all day on internet talking to me. By Monday I was so nervous I could not eat and every time I told her I had to go she cried and every time I came back online she said that she'd missed me. She even listened to me on radio as I DJ on an internet radio station. Yesterday which was Wednesday she added me on fb. Then this other man added me today on fb to inform me that he was really her boyfriend and that she just has a thing about chatting other men up. I suddenly began to feel guilty. So she came online again tonight saying the same thing that she had missed me but I told her you've got this other man with you though. She then started to make excuses that she just had him as a friend on fb but I know he really is her boyfriend.
So what do I do in this situation. She still loves me but as she already has a boyfriend I don't want to be in a relationship now. Should I just be friends with her or should I leave her alone? She still wants to talk to me.
