My friend lived with her boyfriend. He was really weird and controlling, insisting they go to bed at the same time each night and wake up at the same time every morning. So he would never let her sleep in, or if he wanted to sleep in, he would get mad that she would dare get out of bed before he woke up. This meant if there is a game on he wanted to watched, she couldn’t go to bed while he stays up to watch it–she had to stay up until he was ready for bed. This was definitely a red flag–never be with someone who controls your sleep schedule.
