LEt me throw my hat into the ring of men drumped by women the exact line that you've all referenced... I know now that she did what she did because she was afraid of me making her my life (perhaps a legitimate fear) as well as the trial of distance. I just wish she'd have at least attempted to work it out with me instead of dumping me on the spot.
She also told me that it wasn't me, it was her needing to be selfish at this point in her life. This, of course, after telling me that I was her other half before getting on the plane to fly to a different country (exact quote: "No number of seas can make me forget you" - now she doesn't even talk to me!). I can sympathize because I'm sure you all feel used, for having put so much into something only to find out that the other person didn't need you/want you involved with their important life choices... Specifically, that they looked at the pros and cons of their life and came to a rational (or irrational) decision that things would be better off if you simply vanished
It's hard and it sucks... But it's not gender specific. Like I said, I'm a man who has taken this very blow (and let me tell you, with a male ego, it smarts something fierce!). I think my generation specifically suffers from this because there's such an emphasis on hard work overwhelming the lives of successful, driven and beautiful young women such that they feel that relationships are a burden on their futures, making it desirable to wait until age 30 or more to even consider having another person around as more than a friend or friend-with-benefits.
