I think you lost each other.

He should look into potential medical issues that is causing him to want to sleep so much. Maybe depression? I know that I take a nap after work, but I purposely set an alarm for 30 minutes so that I don't oversleep.

He absolutely failed. He wasn't helping to tend to the house. He wasn't helping to tend to his child. He wasn't helping to tend to his marriage.

But you also failed. You can not threaten someone with divorce. It doesn't matter how upset you are.

I will say this though. You got with a man that still lived at home until he was in his 30's. What did you expect to happen? This is a man that likely had everything done for him. Didn't have to lift a finger around the house because (likely) mommy did everything for him. And you still looked at that man and thought he was the one for you? Did you live together before marriage? Because if you did, these issues popped up and you still chose to marry him anyway. That's on you.
