Husband only has energy for sex and video games

I have a very unresponsivle husband. When he is laid off of a job all he wants is sex time and video game time. He doesn't help around the house and is always nagging me about cooking ever 2-3hours because he is hungry. If I'm busy he will not change our youngest child's diaper. He waits till I'm done so I can do it. And then if I sit down for a bit to rest and take a break,he wants me right there by his side so he can be feeling on me. I hate it because I'm already irritated with him not helping or looking for a job. Like I am tired of this situation. He has no drive and gives up on everything half way there. Never takes me out or the kids. Oh an always nagging me about my weight,but he is no model himself. I am tired of it all. And on top of this he wants to have another child.😩🤔 Seriously?!!!! I don't want anymore,not one more. I am tired of being at home  an I want to work.
