And yet they became the "ex" girlfriend. It's because they wanted you more than you wanted them. I agree with mi mai. Only you can make the relationship happen.
Only you can make a relationship happen and sustain.
I hate one-sided relationships, everything feels cold when the other person isn't reciprocating any energy. Some folks are just like that because they're grown up with no social-skills whatsoever. They're always on the receiving end of the stick.... So they'll take whomever "gives" them more!
Those relationships hurt in the long-run because sooner or later that person is going to be drained out of energy and resources!
Only one person is contributing to the relationship = FAIL......
