<human>: Obvious throwaway is obvious. I live a 1.5 hour flight away from the girl I had been dating for the past 2 years (but have been best friends for the past 6 yrs or so). When we started dating I lived cross country but moved closer 6 months ago. 

Since then we have been able to see each other every other weekend or so but I suddenly realized a couple weeks ago like I'm missing out on everyday things like being able to randomly go get ice cream and told her I was breaking up with her. 

She was horrified that I never discussed it with her and I get that I messed up on that front but I don't think this will work out. She's in school in her city for another 2 years and I'm unwilling to move there. She offered to spend a significant amount of time here since many of her classes are recorded online and she doesn't have to be present but I think that's too much effort to make.  This is my best friend and someone who I still want to talk to all the time and eventually be able to hang out with again.  I just don't think hurting myself and her again when this doesn't work is the best way to go.

Background: we really do love each other and had been talking about being engaged in the next year or two. She's absolutely amazing and I am so happy when I'm with her, but the way i operate is to minimize risk rather than maximize happiness. She's mad at me for not wanting to even try her solution but I say it'll just get both of our hopes up and then we'll be freshly unhappy in a month or two when it doesn't work. She insists she thinks it will work and we should at least try. Am I wrong here?

New to posting here so let me know if you need any more info. Thanks for reading!
