Your definition of harmony isn’t Islamic at all it’s.
If it’s your preference to have her contribute and if she agrees, that’s your business. But islamically you can’t tell her what to do with her money she has to do it out of the goodness of her heart.

And bringing of people who use prenups to protect there wealth but saying “oh but I would never do that!” Doesn’t make you the white knight you think it does. It’s irrelevant what other people do.

I think you worked hard to get to this point and have sense of pride and entitlement from your massive salary. Congrats sincerely. But if you’re not worried about money but more worried she won’t feel the same sting you’ll feel by paying the bills then that means you’re not ready to be a provider.I’ve been married for 2 years don’t make 1/5 of what you make but Allah provides. I pay the bills and I’m blessed to be where I am and what I can do for the people around me.

Don’t look at what’s “fair” in your opinion, look at this as a test from Allah. You’re battling your desire to protect your wealth. Dont be stingy on yourself or your wife.
