Double standard or not?

So a little back story.. my husband was unemployed and only receiving the ctc for about 4 months where i covered all the bills ( I had done this previous as well ) and only made him cover a few things our bills are about 1300+ he got 600 in ctc I would ask for only like 200-300 to cover bills and so we both had money to spend. However my extra money went to all the house hold things shampoo, diapers… paper towel.. he got to do whatever with his and we don’t share finances he doesn’t want to. P.s I’m pregnant

Ok fast forward to where we are today my baby was just born, I don’t work but get child support ( how I paid the bills ) he is now working making triple what I get in child support and at 1st still expected me to pay most the bills. I flipped out… I was like I shouldn’t even have to be paying half of these bills when I raise the children we now have 2 together and he has 2 daughters of his own and I have 4 of my own. Mind you I buy everything still for the house and kids clothes, shampoo… you know the list… so I finally was able to SAVE UP $60 to go get a pedicure before having the baby. He had a big fit about this that I could spend my money that way. ( swollen feet and all )

Now his work friends and him want to buy rv cars to race at work ( they have a lot of down time sitting on their butts I guess ) I think like the ones you get from Walmart my 10 year old plays with…. No he is talking about a $200+ car off Amazon plus all the parts to make it faster and make it look cool.

I feel he has major double standards he made me quit my job to raise my bonus daughters, My kids have a healthy schedule with there fathers where I could work and my grandmother would watch our 2 babies but his girls are a bit out of control and it’s hard to find sitters for them ( he made promises of paying the bills and a better life if I quit to be a stay at home mom ) this was before he was jobless for the 4 months the 1st time ..

Am I wrong to be mad that he wants a $200+ rc car? Am I wrong to be on my toes about not sharing finances. Like he demands to know how much money I have but if I ask him he says things like I got a few bucks or why or I’m not broke.

We are married raise kids together live together and this all seems weird to me. Oh not to mention he completely disregards that I paid most of the bills since we got together 2 years ago and that he moved into my paid off home. It feels like he belittles me financially now because he is actually making money and that I can’t spend money on me at all. Everything I have has to go to bills the house or kids and I don’t get much. He gets pissy or thinks he needs a prize for buying stuff for the house.

Am I wrong?? Or is this messed up and I definitely have said something to him about all of this but Now he is showing my oldest son the stupid cars and saying oh I can get one if mom lets me.. like I don’t want to control his money but why yell at me for saving money to get my nails done one time in 9 months and then buy a $200+ rc car??? P.s yes I still paying bills.
