Ok here goes, what should i do in this situation with my ex?

it sounds like to me that you really cared a lot about her. if she can just forget about you that easy she doesn't deserve you. if she really did meet someone which it sounds like she did. and she can just drop you like that she really didn't care that much to begin with. if i were you i would stay away long distance relationships. they don't work to often. find you a girl/women near you who deserves you. good luck. hope i helped! p.s i wouldn't attempt to get in contact with her. and if and when the time comes that shes trying to contact you. stay clear
