<human>: Give me the gist of the text in a nutshell

My ex gf left me when i went away for work. She got feelings for someone else. She ended it for him.  I'm living my life and dating again. It's just something I am curious about. 
She doesn't text me anymore, she would text me her problems before and small texts like that. I cut contact with her and now she is very cold and thinks the worst of me.  So I'm leaving her be. Let her new relationship either grow or fall apart. 

They have been dating for three months now. Her and I were together for three years. She is 22 and I'm 26. He is her age.  

So given the time and the circumstances would it still count as a rebound relationship? 

If so what should i do.  I'm out there and living my life and having fun again. But a part of me still wants to see if we could work it out. 
She still thinks I'm staying across the country, when really I plan on moving home in the next two weeks.
