Am I being too emotional?

I have a 15 month old and am due in January with our second. My husband barely helps. I quit nursing to become a nanny so I could stay with our son. So I watch him all day, come home and cook dinner while playing with the baby, give him a bath feed baby dinner and my husband will play with him for maybe an hour (on a good night) before bed. He has man nights once a week to go hang out with his friends. Then he usually has a friend and his sister over another 3 or so times a week. He now drinks every evening so I can’t trust him to ever even pick our son up if he gets off work early bc I don’t trust that he hasn’t been drinking before coming to get our son. So I just don’t let him drive him. I do literally everything alone. Some nights he’ll be home and eat dinner with me if his friends leave early and his sister doesn’t come over. And during the weekend sometimes we get one of those days where he doesn’t have someone over. I clean the house, I pay the bills (from our joint account) so those are paid on time, I grocery shop, I make dinner, I picked up furniture for our newest baby, I take care of our oldest son without help (minus that maybe hour he gives him some days). But my husband acts like I am overreacting or being dramatic or anti-social when I ask that he spend less time with his friends and sister and more time with us. Am I being pregnantly hormonal? Or is the way I feel valid? I don’t even know anymore.
