In your OP, there are many telltale signs of the deeply held beliefs and attitudes you have that are going to make you a divorced man.
You start by talking up your financial contribution: "It pays pretty well", "this kind of income". That means you deep down think your financial contribution is paramount, and that it buys you leisure time that your wife pays for with her labour, energy, and time.
That's not a partnership: that's you putting yourself at the top of a domestic hierarchy, where you are the boss and she is your servant.
"When im home I try my best. I get the little one to sleep. Sometimes as soon as im home from work."
Here you signal again that you think you DESERVE leisure time. You resent having to immediately pitch in.
"[After putting the youngest to sleep and cooking], Im often moaned at for not running around after all this to clean the kids mess. I understand she is stressed."
I don't think you understand at all how stressed your wife is. It's likely not just the physical tasks that are wearing her down. Given your work hours and the way you talk, I am certain that you do NONE of the mental and emotional labour for the family. This is an enormous exhausting burden that is invisible to you, yet it is the core effort that keeps the ship sailing in the right direction. Look it up: "mental labour".
Being moaned at: you should be working with your wife until ALL the domestic duties are done for the day and you can then both collapse on the sofa. This is what my H did when we were in the trenches with small children: he would come home and immediately take over the kids while I got in some exercise. He or I would then cook, and then we'd eat and we'd both clean up and get everything ready for the next day, and then we'd both fall exhaustedly on the sofa and talk or watch some TV. He NEVER sat down on coming home and expected me to keep running around just because he'd had a long day. He wouldn't have dreamed of it. But if he'd had such notions, I would have thrown him out, because I'm not his servant and he is not my boss and I expect him to helm the family ship with me.
"She works every other weekend so on them days the kids are solely my responsibility."
And? Sounds like there is hidden resentment there too. "Poor me, I never get a break". Instead of seeing these times when you have the children as an opportunity to enjoy them and make up for you barely seeing them during the week.
"When she gets home the criticism begins. Ive hung the washing up but its wrong and wont dry properly. Ive put the next load in but its too much or its the wrong colours. Ive done dinner but made some mess in the kitchen."
This is weaponised incompetence. That is when someone deliberately does a task so badly that someone else takes it over and keeps doing it for them. Do you do such a shitty job at work, and not listen to your colleagues telling you how NOT to do a shitty job? NOPE. Yet you do this at home. That signals a fundamental disrespect for your wife.
That disrespect will get you divorced.
"Im not saying im perfect. Im saying I try."
You're not trying hard enough, and basically it's because you think you're better than your wife (because you bring in money) and therefore you are entitled to your wife's labour, energy, and time.
"The lack of appreciation then puts me in a bad mood"
What, do you think she should give you a medal for working with her to raise the children YOU agreed to bring into the world?
Your sense of entitlement and self-importance will get you divorced.
Also, you being in a bad mood is you trying to bully her into accepting the bare minimum from you. You ADD to your wife's burden because she has to manage your moodiness as well as the million other things she has to do and think about.
"We cant have conversations about anything because shes a bigger victim being home more with the kids."
She is the one who has the sharp end of the stick in this deal. Working, including working long hours, is easy compared to the day-in day-out exhausting slog of being the one at home with the children.
"Sje isn't perfect though when it comes to domestic chores just like im not."
If she's not good at something, then do her a favour and take that task over for her.
"I wouldn't dare criticise though."
You're point-scoring in your head. How infantile. No wonder she's dreaming of divorce.
You should see a therapist to work on your self-entitlement, your view that you are more important that your wife, your inability to empathise with your wife, your desire to see yourself as the victim, your need for praise for doing normal domestic tasks, and your use of moodiness to extract what you want from your wife.
Otherwise, you will become a divorced man.
