first, really feel sorry to hear that
but, it not your loss but his, in my opinion
cuz you just lost a guy who dont love u, but for him, it is a girl who loves him,
see, seems he lost more than you...so it is unecessary to feel sad about it any more.
btw, if i have to face that situation, maybe i will feel a little bit happy for i realize the real face of the guy before i love him more
anyway,just cheer up, and the world worth us to love.
