Well, DB, it's a great question. It's just that until your W is ready to acknowledge conflict avoidance is a problem, it's not a problem to her.
The only thing you can do is to detach and continue being a great guy - being the guy that she knows might get away if she doesn't get with the program.
Something tells me you can do this.
Thanks Betsey. It was wishful thinking on my part. A light bulb went off when I read that.
