What makes men stay up all night gaming or do chores or whatever?

I’m a stay at home mom with an infant. I’m exhausted, and all I can think about when I’m done with the day is coming home, eating dinner with my family, putting my baby to bed, and then going to bed myself. <br><br>My partner is a different story. Every single day he’ll put our child to bed around 7 or 8, then stay up till 3 or 4 in the morning, and then he’ll sleep in till 10 or noon. Sometimes he’ll use that time to game. Sometimes he’ll work on stuff around the house. Sometimes he’ll watch TV. I don’t care what he does with that time. That isn’t the problem. <br><br>The issue is his sleep schedule and the fact he sleeps in so much. He could be getting stuff done during the day that needs to be done, chores, helping with the baby, etc. But he doesn’t. He chooses to stay up all night and then sleeps in till almost afternoon. It’s so frustrating and I’m tired of going to bed alone every night and waking up worried that he’s not there next to me. I don’t understand why men do this
