<human>: A girl I like broke up with her boyfriend for a few months and I started to talk to her more. We were a long distance from each other over the summer, so I could not ask her on a date or anything, and I wanted to introduce my romantic interest slowly.

Now we are in same city again and she is back with boyfriend. For some reason she is also being very, very nice to me, like more than she was before the summer.

What is the best way for me to react so that I seem as appealing to her as possible in case she becomes single again.

From my experience, even if I turn a girl down, I get some urge to intereact with her again if I see her being confident or having fun with friends.

Is this mentality so messed up...that I'm waiting for her to become single?? Also, could she be being nice to me so that she doesn't completely break ties if her current boyfriend doesn't work out? Do women operate that way?

Can you give me a shortened version of the text?
