To clarify, before we were married my wife had a job and paid her own bills. When we got married our accounts (and bills) were combined and we paid all bills out of our joint account. She stopped working when she was pregant with Randy and put on bed rest and has worked a little since then.

So to answer your question more thoroughly it hasn't always been 100% but it is now. I'd say before marriage it was about 25% since I'd only buy food and other crap. She paid her bills and bought her own stuff.
