It depends on what road you want to take. If you consider all of your options up in the air, you are considering the mere possibility of the relationship to be up in the air as well. What I suggest is instead of worrying about things, prioritize. Is it more important to you what you are doing and where you are going. Or is the possible relationship more important. Choose one. Whichever is greater, go with that and stick the rest on the back burner. There is no sense in wasting emotion on a 'might be' relationship if your future career is of grater importance to you.
You better exchange contact info, and make plans to keep in touch. Lost opportunities for friendship are regrets that you will remember for the rest of your life. At least that is true in my case.
