I'll make a long story short here:
Last year in college I met this girl who I became close with. I told her I had feelings but she clearly didn't like me that way or wasn't ready (she was still on and off with an ex at that point). I decided to stop talking to her but she kept popping back in my life, adding me on IM (she never ended up talking to me) only for me to keep deleting her time after time. The deleting part probably wasn't a good idea because it showed I still cared but I guess I still did have residual feelings for her..
Anyways, she just posted on my facebook timeline saying "hey, how are you

when are you back? we should meet up for coffee!"
I told her to inbox me her number, she did and is trying to start conversation with me.
I really dont't get her. Maybe she really does JUST want to be friends but I don't think I can do that b/c I know I'd get feelings back. How should I approach this situation?
