Kind of really don’t know how I should be feeling about this so was looking for a little feedback

So earlier this year me and the the girl I’d been talking with over a year broke up over some kind of stupid stuff that was happening with another guy that she knows. Yesterday she messaged me after we hadn’t really been talking but still kind of staying in touch as friends that she was stressing out about some stuff. So when we talked later that night she was saying that she isn’t really happy with the way things were going between her and the other guy and that she regrets not spending more time with me to see how things were going to go. The bigger part of me is super excited that we are talking to each other again but then I kind of feel like she is just like rebounding onto me or something like that. I’m probably going to at least start talking to her again just to see how things go but for some reason it also kind of feels like maybe both of us are just kind of desperate. Before we broke up though I felt like we really had something good between us so I want to see if we can pick up where we left off and just let fate decide what happens next.
