DH has always been an early bird and I've always been a night owl. We used to meet somewhere in the middle, but over the past few months he's started waking up at 3-4am and falling asleep at 6-7pm (he's snoring on the sofa as I type). We both run our own businesses, so it's not a matter of shift work or needing to be in the office at a certain time.
I know what's happening: he wakes up early feeling stressed about work, can't go back to sleep, and is then understandably knackered before we've even had a chance to sit down for dinner. However, I don't know what to do about it.
It's completely destroyed any quality time. He's also very sanctimonious about waking up early; he seems to think it's more virtuous than working late into the night (which is when I'm the most focussed and energetic, and get the most done). Apparently I'm the one who's in the wrong because I go to sleep and wake up "late" (late being 8-9am wakeup having stayed up working until 1-2am if not later). His attitude feels very Victorian. He's not generally a mean or condescending person, but for whatever reason, he likes to lord this particular issue over me.
I've even tried sharing research that shows being an early bird vs. night owl is genetic - not a matter of laziness or discipline - but he won't budge.
I think there's two problems here - (1) our quality time is practically nonexistent now apart from weekends, and (2) I'm constantly being made to feel less than for having a different sleep cycle.
Any ideas how to approach this?
