Husband and I split everything down the middle, I’m like $100 late on mortgage..he acts like I don’t even contribute

when I was 5 years old I remember my dad telling me the reason he divorced my mom was because she spent too much money..(in reality he cheated on her for years)... it really messed up my 5 year old little brain.. when I started dating, I made it a point to always offer to go Dutch. Always splitting EVERYTHING evenly down the middle.. I often found myself in positions where I paid more, many times being in relationships eventually where I paid for everything.. I despise mooches.. i was really grateful to meet my husband, a successful lawyer, funny guy.. smart, charming good looking who I fell madly in love with..I vowed to always pay half, and our relationship was a true equal partnership. There were times in our relationship he always made more, oftentimes over six figures.. where there where times I made only $14 an hour.. I always made it work though...fast forward 8 years.. I’m in a spot now where I do all of the cleaning drive our daughter to and from daycare 1 hour each was so 2 hours of driving a day.. I’m also running my own business which right now I’m sort of not bringing in as much as I was.. and there are times where I’m like $100 late, not even short EVER, maybe $200 late at the absolute most... on our mortgage..I also pay half the bills..half of daycare.. half when we go out to eat.. I’ve supported him when he was unemployed for 2 years. I thought with him making so much money and the fact that I’m growing my business (not making as much and have to pay employees and expenses) and hoping to make a lot more one day.. that he’d support me especially with all the hard work I contribute with our daughter and household chores.. and he likes to point out basically how much of an issue it is that I’m short on the mortgage by that small of any amount.. he acts like I’m some sort of money grubbing mooch, and the truth is I’m not.. I know a lot of wives who don’t even work.. and I feel the gratitude isn’t there for what I do contribute.. I’m getting to this point in my life.. where I feel like I made a mistake. We bicker about things like the gas it takes to get to my daughters daycare, paying half of grocery bills which we always split.. if we decide to get the nice toilet paper it’s an argument like “okay do you want to spend the extra dollar, you gonna pay half?” Etc... there are some things he pays for like health insurance.. it’s expensive I get that... but I’m at this point where I’m tired of the lack of gratitude and I sometimes think about how any guy would be so grateful to have me and would appreciate how much I DO contribute.. I’ve never stolen money, or spent his money or asked for money...am I wrong to feel like he’s a cheapo and needs to grow up? I’m at a point where I want to separate because it’s just like dude.. your a lawyer for Christ sake, you make 2x what I do.. I hold my own financially and you act like I’m some sort of money grubbing mooch..
