Dude, have faith mate! Sometimes things work out for the better. If this girl didn't dump you, you might never meet your proper real soulmate. Trust me, there is someone better for you out there.

But before you do that, if I were you, I would definitely like to get some clarification on why she just ignored you all of the sudden. Did any of her friends talk to her or something about you (something you never told her before) reached her ears?
