My FI drives me insane. I like going to sleep a bit earlier. We both wake up at 5am for work and I like to get at least 8 hours of sleep. But I don't like going to sleep alone. I don't even ask him to physically fall asleep at the same time as me. I am fine with him watching TV in bed for hours. If he wasn't going to bed with me, he'd be playing video games, so it's not like I drag him away from anything important or productive.
It is like getting a 5 year old to go to sleep!!
Sorry for the vent!
