Is this major rebound or what?

So, I am currently seperated from my spouse. It will take about a year to file for a divorce, we have to show a year of seperation. I all the sudden have a bunch of guys knocking at my door asking me out. There is this one guy in specific who I really like and wanta see something develope, but the thing is he lives to far. He is studying to become a doctor and it seems impossible right now for this to work. I know he likes me a lot ,but for some reason he acts cold at his own will call. Sometimes he'll be sooo crazy about me, and other times he'll act nice, but aloof and off in a different world. He told me not to acpect anything from him because he is studyin gnad I am gong through a divorce so things should go slow and he wont have tim right now for me. he was honest, but at the same time he's on of those players boys which u can see. Why m i so attracted to him? Is he REBOUND man? I am not sure I know exactly what a rebound bf is. What should I do?
