So frustrated need to vent

Husband is actually on his way to help his brother put his fence up all day after I cried to him last night about how our twins just complain literally all day long no matter what we are doing, they give me attitude the entire day, and they fight with each other the entire day. I’m 34 weeks pregnant and I need help. He’s like “well my brother has helped us in the past.” I’m like and we’ve already returned the favor??? And I help you daily by raising our twins and carrying our third kid and keeping our house up and working on top of all of that??? And he’s like “he’s going to help us in the future too.” And I’m like so am I??? Like my foreseeable future is continuing to burn myself out by raising your kids and you.... and then birthing our third kid....... and then continuing to work and keep our house up... I need help too dude. He’s like “you should’ve told me you didn’t want me to help him when I made plans to help him. And I’m like I just want you to be considerate of your wife on your own without me flat out asking you to be????! How does he not find anything wrong with this
