Been with my wife going on 25 years (OMFG!!)
I don't like liers, Can't imagine her being any different.
We have never had money issues, we have an us account for all the family bills, we each put in equal (or what we could) that deals with all the expenses plus a bit.
The remainder of her cheque is hers, and remainder of mine is mine.
We knew at the beginning either of us could torch both cheques...
And for the record she was the bread winner for the majority of time, although it didn't seem to matter much.
She got her toy's, I got mine and somehow we paid off a house, did some reno's, wanted for nothing and lived life happily.
So the moral;
-Don't lie.
-Look after your family.
-Buy whatever you want and don't hide squat.
