What are SO's gripes about you...and is s/he justified?
I work a lot.
FI works nights. He used to get home after midnight, say hello, and fall asleep on the couch. I started work around 9 am...and would pretty much work until 2 am some nights. It bothered him that I worked while he was home (even though he was sleeping). I also worked sometimes on the weekends (even though he works Saturdays). So, I started making it so I stop working by the time he gets home (around 10 pm now) and I don't work on the weekends at all. He still complains.
I thought he was justified before to an extent. I don't think so now. I don't think he needs to care how I spend my time when he's not home. If he was home with me, I would spend the time with him....I have nothing else to do.
