Husband spends all weekend on the couch

I just need to vent because I'm cranky. I take care of everything. The entirety house, kids, pets, grocery shopping, cooking, cleaning, house maintenance, yard, trash, my vehicle... You get the idea right. Like I'm not exaggerating, my 32 year old husband ONLY does his own laundry and cooks food for himself and that is no joke it. He doesn't even clean up the crumbs he leaves on the counter. I get it, he works 9-5 pm Mon-Fri and pays for everything. But I've come to hate weekends. All he does is sit on the couch and watch TV. That's it. I hide in other rooms or outside with the kids. And if someone is a little too loud he gets cranky "hey I'm watching a show here". He didn't used to be this way. He used to take initiative, come up with activities but Omg, he's so wrapped up in himself he claims he doesn't even know what to do unless I specifically tell him. For Pete's sake, you're a grown man, you're 4 year old daughter has more initiative and clue of what needs done! So here I am nearly done with the 5th month of this pregnancy and I'm so cranky with him and don't think he'll figure anything out so I've already planned on the kids to help out when the baby comes. I'm exhausted. But I just have to bite my tongue and be grateful for what he provides for the family. Not how I envisioned marriage and family 💔 can't change a person that sees nothing wrong, or needs step by step instructions to find a reason to get off the couch🤦🏼‍♀️😔
