You're away for 5 days with your partner's family; other than time spent with your partner, do you feel guilty for not hanging out with her family (all of the rest of the time)
If I want to go off and read a book, take a nap, or play online for a bit, I feel bad. My partner makes me feel bad and I am hoping that I am not being antisocial. Sometimes, I just need alone time. Five days with your partner’s family is a long/lot of time. Most of my time is spent with them.
She doesn’t see them all that often, so she may want to spend her free time with them. I understand that.
