Melo - my man. Sorry that your sit has dissolved. Maybe you will find some comfort in knowing that the inability to repair the problems for you two are hers - maybe. There is nothing you/me/we can do about the WW. Fight on. The only advice I can give you that is worth anything is: you/me have to be a stand up guy(s). You and I need to give up on the actions that make us look bad to ourselves, the W, our kids, etc. Not snooping, trying to influence/manipulate, being a push over, etc these actions hurt us as much as they hurt others.
Once you give up the "physical" i.e. snooping, arguing, etc - you/me might find giving up the subtle will be easier.
It ain't easy. I often have to say to myself - was what I am feeling/saying could be interpreted as pushy, weak, deceptive, manipulative, controlling, etc. etc.
Yes, it's very hard to grow a pair and to GAL. Perhaps giving up one bad behavior might help launch a new you. You might find that ditching one bad behavior - swearing, crying, whatever is not only a block between you and her - but your kids, family, God, etc, etc.
