I can't imagine the quality of the marriage where this has become a 'Do as I say' issue.
How is your marriage overall @MrsPuddle ?
I think, being honest, you expected and hoped posters would say your H was wrong. This is because you were a little disingenuous with your subject line and you've not engaged with a lot of questions so no one knows the full story to this.
However, with this age gap, most couples would have a conversation - long before 60- where they said something like -
H- 'I don't want to work beyond 65. Let's look at our finances and see if we can manage if you stop work at 55.' Let's decide what we both want - for ourselves and for us as a couple.'
He could also have asked if you wanted to carry on working beyond 55.
And what you (as a COUPLE) wanted to do when he was 65.
That might mean him doing his own thing while you carried on working longer. full or part time.
Or not. Some women aren't ready to retire at 55.
I can't get my head round a husband dictating how long his wife should work. It shows a complete lack of communication about your future hopes and dreams for the rest of your lives as a couple.
It's telling that you've come to ask strangers about this (but only given a one-sided view) and not said what's happened when you've talked to him about it.
Does he not want to spend time with you?
