Husbands at a bar while I’m at home with our kids

We have a one month old and 2 month old. He left for work this morning and downtimes for lunch I know him and his coworkers so have a beer every now and then and I’m sure doesn’t tell me every time he does. Not what I’m upset about. It’s the fact that he posted a picture of his beer on the bar and it made me mad. I mean, he gets to do that whenever he wants, everyday if he wanted and I can’t. I know he didn’t do it to rub it in my face but that’s what it feels like. It just hurts my feelings, maybe it’s the hormones but idk why he can’t just keep things like that to himself, especially now when he knows I’m at home struggling with our babies.
