I did, although he married me for love I think. We're not massively wealthy but very comfortable, he earns about 3 times what I do and pays for pretty much everything. He supplies and keeps my car on the road and pays for the house stuff.
I work but my money is my own.
We rub along together, more like friends than husband/wife and while there are things that frustrate me sometimes, I like my lifestyle.
I think a LOT of people marry for money/security.
