How did y’all get past the newborn stage!!!???

This is my first baby and the new born stage is soooooo freakin hard I don’t know if I’m doing things right and when me and my husband first came from the hospital he was really a lot of help with cleaning bottles and feeding her and changing her but it’s like he lost interest and feels like everything is a chore now … or like he doesn’t want to do it but he will… he gets upset when I get upset when he’s on the game and today he went out with friends for the first time and left me home for like an hour by myself with my 2 week old and it’s just sooo hard idk what to do bc I know he goes back to work doing overnight in 2 days so I’ll be doing a lot just by myself…
