Moving on

I have made ammends with a long time friend that I still have very strong feelings for. I wonder if it's too soon to let my guard down considering the painful relationship I just got out of. There are many things that stand in our way. He lives about 3.5 hours away and he was the first person to break my heart. The only reason I accepted his offer to keep in touch was because he never tried to hide the fact that he messed up. Also, we were 19 at the time and very naive. It's been about five and a half years later, and I think it may be worth a second try. I don't want to rush anything, but I don't want to miss out on something that could be good for me.
