OK OP, 10 years ago (when you went back to work), your children were a lot younger so circumstances that applied then won't apply now.
He presumably earned a lot less 10 years ago than he does now too so if you earn enough to afford a good lifestyle now then, if you went back to work, you could presumably afford things like a cleaner to ease the load at home?
Just trying to think of solutions because I think your self esteem would benefit from working.
The bigger problem is how this came about though.
When i was a child, my mum was a SAHM/housewife and didn't work until I was around 15 when she had a part time job. And, I'll he honest, we never regarded her as being 'lesser' because of it. Gifts were always from our parents and we never thought of it as my dad earning the money - dad went out and earned money; mum took care of everything at home. They were equal in our eyes.
Amongst my friends, I'd say there was a fairly even split between mums who didn't work outside the home, mums who worked part time in retail/office jobs and mums who had professional careers. Not that we really discussed it but, when we did, these were just facts about our families and didn't carry any value judgements.
So how has this evolved.
