Haven't read the full thread and OP hasn't been back, but I did want to throw my two pence worth in about the "uniform job" comment.
I don't think it's necessarily about her disdain for such roles, I think it was an expression of the imbalance of their relationship and lifestyle expectations. He's reluctant to help her retrain on his dollar, wants her to financially contribute and thinks she should just "get on with it"
I'm in agreement that a job / career is a good thing for her financially and future security wise, and I speak as someone of 55 who was recently widowed after 7 years of caring responsibilities and self employment (current economic climate not favourable to independent retail), and is now staring down the barrel of penury.
Yes, I stuffed things for myself by always dropping everything for family commitments and my unexpected circumstances have me kicking myself ever day that I didn't do things differently. But it is what it is.
I know it's a bit different as I don't have young children, but I empathise at the lack of confidence etc. It's a tough old world out there.
Back to my original point - if there is a power imbalance overall then possibly the DH would prefer her to take any minimum wage job going and doesn't appreciate that she will have to be flexible in areas like retail and hospitality, and the OOH childcare etc may well mean any financial benefit is swallowed up if he is not in a position to work round that.
If it's about working on principle, rather than for the OP and the family's benefit overall that's a moral debate they have to resolve all round.
No doubt there are opportunities out there, but depending on region and infrastructure, after a nine year break from the job market it may be difficult to find something suitable that fits the OPS skill set.
Not that she shouldn't try. I just think it's overly simplistic to say "just get a job and make it work" especially if the relationship dynamics are complicated.
