Lovely Lady,
Clearly whatever rocks your boat is your business and if your generally happy and just having a "fuck you" moment, and feel better after your rant all well and good. Your life your choice. the following is written assuming your not at risk of Domestic Violece or the kids. If you feel you may put yourself or your kids are at risk, seek professional support.
If however your actually thinking, fuck this, I can add a few things.
I used to be an equal financial partner, now I make no financial contribution as I do all the kids shit, shopping cooking etc etc Blar Blar Blar, it's kind of my choice for now.... Anyway.. so my DH (18 years, I'm also in my 40s, professional couple) he works 40+ hours a week. He also when not working the weekend (shift worker) he gets up and takes the boy to Rugby or the girl to soccer. He will cook, put the washing in or out. Etc etc. So go me, lucky lady with a fab husband. But that's not why I'm replying.
Okay, time to try and have a chat with the DH firstly. Point out he can only do what he does because you do what you do. That you are not happy with the situation and you want and expect change. Be specific about what changes you require and a time frame. (What do you want? Something more tangible than "I want you to help more") Try - I need you to take the kids to sport on Saturday, I want a date night with a baby sitter at least once a fortnight, where we go out without the kids. You need to remember to tell and show me you appreciate what I do. I don't just know it. You will no longer tell me to "shut up and be a good wife" it's disrespectful, it offends me, it's not funny and needs to stop today. You need to be home from work and put the kids to bed at least twice a week.
The bloke genes respond better to fact rather than emotion. So make a 2 column list with everything you do, with approximate times taken.
So proving you work about 100 hours a week. (Cost it as if he was paying for it, ie: If you didn't do it, to buy those services @ so many hours a week would be)
Then list the downtime you take.
Leave a colum for him to do the same.
He will come back with all the usual bullshit excuses, so here is where you DONT LOOSE YOUR SHIT, calmly tell him that you wanted to have an adult conversation, that you are going to leave the house now (with the kids left at home) and come back in a few hours after he has had a chance to think. Then go, to the cinema or a cafe and read...visit a friend but don't then just rip into the DH. Actually make a list of anything he does do to help, reasons why you like being with him. Don't get pissed!! Text to say you will be home at ......... And want to find an agreement.
IF when you get home he agrees, apologies etc. Don't push further for now. Thank him for hearing you and tell him you will hold him to it.
This is pretty unlikely but can happen.. If he continues to be an ARSE, tell him you need both of you to go to professional counselling.
I think it's pretty interesting that most men say they have no idea that their wives have been so happy that they had planned to leave right up until the bags are packed. Most woman say they had sent clear signals for 12 months at least that they were very unhappy and wanted things to change. It all comes down to communication. As woman we over state in our heads how much we are communicating, we think we are being clear because we are doing the pissy silence.. Blokes think "oh excellent the sports on" We say things like "I need more help" and so he thinks "go me, I washed up job done. By the time we get to the specifics we don't like them enough to care and just want them fuck off" we put up the barriers and they are standing on the other side saying "what did I do" WE all know the answer is "not fucking enough sunshine" but they genuinely don't get that. You have to be specific, you also have to be honest that your not saying BLAR when you mean BLar BLAR BlAR. This way he can measure when he has done good. It sounds like children, but stick to really simple language and don't assume anything.
Anyway so this turned into a bloody novel, sorry. another thing I do which is very useful, is to go away with the girls for a long weekend. Give him notice and say your going, when he does the whole - whose going to look after the kids tell him to work it out for a change like you do all the time... However you MUsT go as long as you know your kids are safe. (So what if they eat pizza for 4 days) Oh and no preparing stuff for anyone before you go!.
