<human>: Condense the text into a few key points

I live in CO and she lives in VA. We dated throughout college on and off and are interested in all of the same topics. I messed up in college and broke things off our senior year out of fear. Things were getting serious and I wasn't ready for a long term engagement/commitment. We still remained friends and would call each other at least 2x a week.

Fast forward to this past week. I went to VA to visit family and friends for 10 days as part of vacation. While I was home, I received a text from her stating that she wanted to catchup and have dinner. I didn't really think it would go anywhere so I agreed that would be a great idea.

We really hit it off during dinner and eventually went on 5 dates in 10 days. I expressed how I felt really bad about breaking up w/ her and she agreed that we should try and work it out. Her logic was that if we still have feelings for each other after not dating for 1 1/2 years that it was probably  a good sign we should be together. I was onboard with this idea and we have been talking/skyping/emailing almost daily since I went back to CO. 

The thing that worries me is that I have never been in a long distance relationship before and don't really know what to expect. I am on the fast track at my current job and am about to start my MS in CS. I know this is my last chance with her and we both really want this to work out. Any advice?
