Just a little help

My lovely spouse has to be the laziest and rudest person lately. I have a two and a half year old daughter and I’m 18 weeks pregnant with my second. My two year and a half year old comes from an abusive relationship I escaped before having her, the real “father” is not around because he is scared of a restraining order I’ll get because he doesn’t want to lose his cushy navy job. My spouse and I met when she was 4 months and have been together since (we were together in high school but when I went to college we both took time to explore our lives without each other and ultimately came back to each other). Im about to start a new job this week so I can bring in some extra cash so we can save it away. My spouse has decided our two year old no longer should go to bed with her water cup since she gets up so much to pee afterwards (pottytrained), which has been a two week no sleep hell for me. While he gets to pass out whenever he wants and takes naps whenever on weekends. While I’m left dealing with her, groceries, laundry, dishes, taking care of our animals, cleaning the house, etc. But we also have to be quiet because if we wake him up all hell breaks lose. How am I suppose to keep a very active two year old quiet? Beats me. Like tonight it’s 7:30 which is her bedtime. I’ve picked up the house while she brushed teeth and her hair. I put his clothes out for the next day and packed his lunch. I fed the animals and turned out the lights. Only thing for me to do after I put her to sleep is clean the dinner mess and switch the laundry out. But my lovely daughter decides as she is picking out her stuffed animal for the night (that was the trade for the cup) she was going to start singing baby shark. Loudly. Now usually I let her, I let her express herself and I never tell her to shut up because she was basically nonverbal up until 5 months ago and I never want to discourage her. But of course he wakes up and asks me to get him water and as I’m doing this he begins to yell at her to get in bed and shut up and how he’s about to lose it. No one told you to go to bed at 4pm today. To where I had to do your homework that’s due at midnight. To where once again I’m having to try and keep a two year old quiet. Now it’s 8pm and she’s finally asleep to where he is now in our room bitching about how she riled him up and can’t get back to sleep. You are a 25 year old man. She is 2 1/2. She has barely seen you since you got home other then dinner and all you do is yell at her when you did wake up. She wasn’t trying to wake you. She wasn’t trying to make you mad. His temper and patience are gone. He literally explodes at the smallest inconvenience now a days. To where I told him this weekend after he yelled when I asked him to help me bring in groceries that if he didn’t shape up soon I was going to stay at his sisters for a few days until he figures it out.
