Past Repeating Itself?

We have all been there, the whole I love you both, but, I think I love one of them more. Well here is my stand point in life at the moment, I'm stuck between two amazing men. One - a guy I have know most of my life and we never got the chance to date because we were always just friends then he moved, Two - a guy I have only know for a few years, but, none-the-less he has fallen as hard for me as I have for him. So is it too much to just call it quits when your dating guy number two and guy number one falls back into your life and start anew. Or should we try to make the relationship with guy number one stay friends, and stay with guy number two. Or are we going to do what everyone seems to and repeat an ancient mistake and let guy number one sweep us off our feet with ease and risk guy number two? I personally would love to have that book with all the answers, but, nope I am stuck like everyone else. So as I think this through and even as I am typing this the old question pops into my head I have already gone through this and have before lost a different guy number two and had guy number one leave me, so are we all just learning new situations or are we now after so many relationships programed to repeat our mistakes with new people?
