A fair partnership for me works on the idea of putting effort in= jollies out.
No matter what that may look like.
Effort may be paid work, housework, childcare, mental load, financial organisation.
Jollies can be money, trips, nice car, free stuff.
I was a SAHM for years, OH earned all the money for a while, and we both had free access to spend as we needed.
His job was hard, but also involved many trips away, wher evenings were spent relaxing in hotels, or having meals in fancy restaurants paid for by his company with his colleagues.
Meanwhile I was at hpome with no personal income, caring for his kids while he was away, sometimes for weeks on end.
So I would take the kids out for a meal, book myself on yoga workshops when he was home, treated myself to haircuts and luxury items to make my life easier.
He never questioned my spending- not once.
He knew he was lucky to have my support which allowed him career freedoms, while also being a father.
