Now to get off topic a little bit:
The one thing that gets me about this thread is how many talk about different bank accounts, separate bills, etc. I don't understand why or how married people allow that to happen. In my marriage everything is on the table and my wife and I don't keep secrets. If she wants to look at my cell phone, have at it. I have nothing to hide and neither does she. When it comes time to pay the bills, we do it together for the most part so we both know what is going on. If I wanted to have privacy and keep secrets, why get married? I just don't understand that type of thinking. If you want secrets get a room mate, not a wife or husband. Maybe I'm old fashion, but I thought marriage was a partnership and a merging two separate people into one team that works together. Sorry to get off topic on my little rant. I just wanted to get that off my chest.
I'm happily married with nothing to hide and neither does my husband, but we have seperate checking accounts, seperate savings accounts, and 1 joint account. It's not 1950 and I don't see what the problem is with keeping money seperate. My husband makes more money than me and has more of the bills in his name.
It's mostly a matter of convenience, not a lack of commitment.
