Sorry about your marriage going to hell, but I'm a huge believer in these things being for the best. I've never seen people change and I doubt she will either... but at least now it's the next guy that can put up with her.
The sad thing to me is that my 20 year old son is dealing with the same kind of woman right now... and he doesn't see it at all. I just pray he wakes up before they wind up at the altar. Why do we all blindly think that these relationships will get better as time passes?
