OP, for a second, imagine you’re on your own, what would you do? Would you take the job? Or would you prefer to chill at home more?
At the moment, you are thinking and acting for all of them. The thing is: your H isn’t thinking of anybody but himself. The kids don’t know any different.
What is important to you? What do you want to do? Forget about the rest, just look inside for a moment and decide what’s important. Not what’s expected of you, not what you have to do, what do you think should happen.
Childcare, pick up, ferrying, washing, bedtime etc should be done 50-50. It would allow both of you to work and function.
Housework, shopping should be 50-50.
As someone said upthread, don’t underestimate the amount of work your H generates for you. I was married for 20 years, the minute we split up, ine of a sudden I had so much more time on my hands! I have never ever in 20 years with him just came home, grabbed a shower, picked up my book and read for 20-30 minutes before very calmly putting something from the freezer in the oven, ate, put the dishwasher on and continued with my book. That simply has never happened. Because I had to rush home because he wanted to go out/didn’t ‘get the chance’ to do any shopping in, so I had to do it, was too tired to put a wash on or bung a load on. Because I had to listen to his ramblings, because I had to be ready by a certain time in the evening when he wanted to put the telly on and relax, etc.
Now, yes, my DD is older and self sufficient. I don’t commute anymore, because I did what I have been asking him to do for years: you work part time, I work full time, can we please move closer to my work? I went on and did it and it’s bliss!
I don’t have to chase his lazy arse anymore, and that freed up HOURS of my life.
