<human>: Give me a shortened version of the text

I dated a girl about 1.5 years ago for only a week and she didn't want to do long distance (I was going back to school in a different state) so she broke it off. A few months later, I noticed via facebook she started dating another guy. Just last week he broke up with her, and during their entire relationship her and I never spoke. Just today she messaged me on Facebook saying "hey!" and I said "hey [name], long time no talk!" and she said "i know!! how have you been??" and she just seemed really enthusiastic about the conversation. We talked for a little while and then I logged off to do some homework. Does this sudden interest in talking to me again mean that she's trying to rebound back to me or is she just interested in being friends again?
<bot>: ex breaks up with her bf, then she starts talking to me again almost immediately after not speaking to me for over a year. Am I rebound?
