Short answer.... no. But I've probably overstepped just saying that.
If a marriage licence was like a driver licence, then I believe many would not be renewed. Unfortunately once children come along, it is not just a matter of not renewing the licence...
I just am thankful for my hubby and our relationship being so good. Of course, it has ups and downs, and we have "words" but when I'm cranky with him or the kids, it upsets me and I just don't understand how people can live "off centre" continuously. I would cut my losses and get out if I was continuously unhappy (but children and finance complicate even the simple act of "getting out".)
