The girlfriend sounds really childish. To the point I’m wondering if these are very young people, like early teens. If so it isn’t that that don’t care, it’s that they’re very immature and don’t know how to deal with anything uncomfortable and just shove it out of the way and move on to what they can easily distract themselves with.

If this person is an adult, I’m very concerned about their maturity level, becuase it sounds really stunted.
