After I got divorced 11 years ago, I got to keep my '90 300ZXTT cause she wanted the full conversion van. No problem with me for sure. Now I have a live in girlfriend for 10 years (not the cause for the divorce, but I digress...) and the money is separate, the house is mine, all the cars are in my name, and she contributes part of her salary for the household budget. After that, she has her own finances, and I have my own finances. I wanted a 370Z, so I got a 370Z... no issues to report except she loves to go riding in it. The funniest part is - I have a 6MT, so she says "...but I can't drive it!", my response:"Babe, who said you were going to drive it at all...??".
See, I figure it this way: That ring a man puts on his finger, is actually a castrating device - however, every so often one finds a gem of a lady who will support rather than castrate, but that's like 0.9% of the ladies out there... So guys: here's the bottom line: Don't eat the wedding cake, because it drains any sexual life out of the relationship, and don't wear the ring, because it removes any decision making powers you had prior... neither situation is what a man is all about!!!
A bit long and rambly... sorry!
ps: Louisiana is a no-common law marriage state. We have what is called the Napoleonic Code: I Love Napoleon!!!!
