Similar to @GnomeDePlume here - I’m the sole earner and DH is a SAHD.
We realized the combination of my earning power + his hesitation push himself + my being not very good at SAHM (during maternity leave) = more sense for me to push my career while his took a back seat and he took on more at home.
It’s been a strategy that has largely worked for us. Like above, he’s a doer and I’m a planner so him taking care of literally everything at home, and me with a senior career, means we are playing to our strengths.
However, there is some resentment - he and the kids are a proper trio and I sometimes feel not part of that, plus it’s been harder to make friends as I’m not the one at the school meeting other parents. And the kids often go to him first for things now, which stings a little. He also has no idea about financial stuff and we’re starting to plan for retirement etc and it’s obvious it all will fall to me - both in terms of planning and funds.
He is likely to go PT back to work as self employed in the next year or so and could viably build a strong and successful business. But he’s lacking in business acumen and confidence and after years of trying to help him, I’ve accepted that this is who he is, and the effort to find the confidence has to come from him - I’m not his parent.
So for us it works as it is, and I think it’s the best set-up we could have on a practical level, in that his reluctance to really go for it means we have the luxury of one parent at home but still a very nice life via my career. But then hesitation, reluctance, lacking ambition, lacking confidence, could do well, does lead to an undercurrent of frustration at times.
