Me and DP are on completely different sleep schedules. I need to be up at 5.30 during the week so aim to be in bed for 9.30 and sleeping by 10. He stays up past midnight every night but doesn't need to be up until 8.30 for work. At the weekends I really try to stay up a bit later but it's a big struggle. I'll usually stay up til 10.30 unless I'm really tired on a Friday and on a Saturday it'll be 10.30 or as late as I can manage. I'd rather go to bed at 9.30 every night honestly. He doesn't understand that me trying to stay up til midnight feels just as hard to me as it would for me to wake him up at 5am.
Any weekend night where I say I'm not staying up late as want to be productive the next day it just turns into an argument. He's said he doesn't want to argue about it and that we shouldn't have to fight about this. He says it's pathetic that I go to bed that early and we never spend time together and will then be annoyed with me but I feel like I'm fighting my natural sleep cycle at the weekends then have to energy to do much. He will want me to have a coffee in the late afternoon so I can stay up later.
AIBU or is it him? What would you do in this situation?
