Idk how to feel😩

Basically I do everything around the house.

My husband works everyday and his little brother is 16 so he is at school. During the day I’ll clean up the house and do what I can (laundry, dogs, kitchen, lounge room, rubbish) and I’m 21 weeks pregnant and still have no help around the house. They come home and just make a mess of everything, i make dinner and desert as much as I can even when I feel sick or have cramps i still make dinner and his little brother is so ungrateful 😑 but if I don’t cook he will go sook to his parents and I get into trouble, hell when I was 16 I was cooking for myself but the brat won’t even put party pies in the microwave!

He won’t wash his clothes or anything and I’m really sick of it.

I don’t mind looking after my husband cause he works to pay the bills but his brother has no excuse to not help around the house. We have a chore list but they don’t do their jobs and I’ve tried to just leave it so they do it but they don’t and so I end up doing it. Keep in mind it stays for like 3-4 weeks before I cave and do it myself.
