Wow. What a coincidence!!.
I did that with my first wife. She said OK No problem. After 5 years she gave me an ultimatum. Then another, then another, but kept spending the money and buying a bigger and bigger house etc. After 15 years she gave me a final ultimatum. My job or her. The next 5 years were "very difficult" to manage.
Finally I left.
The moral is :-
Think carefully about YOU want.
Never say never
No offence girl, God Bless
