Have you ever felt upset and not care at the same time?

I don't know if it's because I trust her and I'm not worried or that she says one thing and does the other, always panicking about irrelevant shit and turns to the bottle, not me for comfort, if it's how she says she'll be home when I get off work and is drunk at her girlfriends house getting all riled up gossiping and exaggerating problems. Maybe I'm upset but don't care because I'm used to it now and damnit, I give up.
