Being treated well is not mutually exclusive with money.
You can be so poor that you have to skip meals and your partner can still treat you like a princess.
You can have all the money in the world, be a literal Princess, and your husband can still have an affair and treat you like shit.
This is my point. The price of her ring doesn't mean anything, whether it's cheaper than someone else might like or more expensive.
And to further my point about "treating her well," as much as chicken man makes my skin crawl let's not forget: he provides for four kids; he is the one bringing in the main wage; he is the one paying for her holidays and what not; he was not the one who had an affair and he had no loyalty to a partner; and he is the one who took control of the birth control situation and had a vasectomy.
He isn't my cup of tea, his vests make me want to heave and his general attitude and behaviour towards others is repulsive at worst and questionable at best.
However I don't think he is the one we should be looking at when it comes to pulling their weight relationship wise.
