she's happy

Because it sorta makes you feel your relationship wasn't important enough to her to provoke this change back then?

I suppose...I can't tell if it hurts in a good way or a bad way...I started crying when she told me that and I can't tell if it was because I was happy for her or because I felt inadequate.

I dunno...I'm just thinking from my own experience. How you want to save someone or help them change things for the better and it doesn't work and things fall apart and later they do it on their own. And it feels like a failure. Or like you weren't worth their putting in the effort. Or whatever.
