Between a rock and a hard place

[Geminight]

I'm in a bad way. This guy whom I have had my most serious relationship ever with (we had thought about marriage) have broken it off and not spoken to each other for about 2 years now. We met through his sister my ex-bestfriend. We have recently ran into each other again on facebook and she wants us to be friends again just like we used to "in the old days." That's all good but I really doubt my (let's call him my ex fiance) would want to see me or better yet when he sees me will probably flip the fuck out The last thing I want to do is get in another confrontation with him or put either of us through anymore pain than we have already been through. I still love him you know. But I really do want desperately to reunite with the one person who knows me possibly better than my ex fiance does. I don't want to hurt her feelings but I don't want to hurt his either! What should I do??
