Well, I was a “SAHF”–stay-at-home-fiance–when I was engaged to DH. Let me explain. We lived two hours apart, and had recently gotten engaged. I started a job in the social services, but it didn’t work out. I knew I was going to be moving to his town after the wedding, and it was going to be hard to find a job if I was going to be honest about my circumstances: “Hi, I’d like to work for you. But I’ll be moving in, oh, 9 months.”
We were blessed in that my fiance had a very good independent consulting job, and could afford to support me. He said we could combine our finances and I could manage the accounts and work on preparing for the wedding (again, in about 9 months).
Oh, my mom HATED this. She called me a kept woman. We didn’t live in the same house; I kept my apartment and he had his house two hours away. We visited often, always staying in the other’s guest room. I worked on learning how to be as frugal as possible so as not to be a burden to my fiance; I read the Tightwad Gazette a lot and the library was my friend. In the meantime I dealt with wedding preparations and my mother.
It worked out very well for us. I learned about paying bills and balancing a checkbook (neither of which my parents had bothered to teach me), and how to stretch money. I was kept busy with traveling to visit my fiance, or up to visit my mother for fittings, floral things, and also pre-Cana meetings with our priest.
I feel my fiance and I grew very close in that year, and it also taught me how to be happy and busy without a paid job. Which is something that can be hard for new brides when they decide to be stay at home mothers or wives. I did get a part time job when we were married, at a library but quit when we had our first child.
So yes, I’ve been a “stay at home with no kids” but I don’t know if it counts because I wasn’t married yet.

I do know people did look down on me a bit; they felt I was being lazy and leeching off my future husband. He didn’t see it that way at all; he said my job was the wedding preparations, and learning how to deal with money. Something I really did need to learn.
