You may have the prayer memorized but do you REALLY understand the context of it?
I feel you are using your kids to try and control your W. I am sorry if that is wrong but it's how I see things. You really will have to expand about the "mess" your W is pulling them to and how it compares to the "mess" you pulled them in to.
Before you can pass judgement on somebody else you must examine your role as a man and father. I am surprised your priest has not spoken to you at length about that.
You judge your W about EVERYTHING yet when we point out things you have done you say you are sorry, you get it now and you won't do it again. But you do.
More than once you have shown your kids that when the going gets tough you quit (going to Florida, job, drinking, AA) but somehow that is not pulling them in to a mess. And trying to control what your W does by saying it is for your kids is also pulling them in to a crazy ass mess.
