Married guys - car budgets and honesty

WOW! Talk about opening a can of worms. Not married, but many close friends both male and female. My life and money is mine to do with as I please. Don't have to "Check with the Boss". That line really bugs me when I hear it. A friend of mine once said that he didn't realize the woman he married became a detective. Digging into his past, present or future. Looking through his cell phone for numbers or calls. I'm not saying marriage is a bad thing, it's just not for me and I'm okay with that.
