Hi U-turn. From your description of your talk with your W, she is clearly still wayward and unrepentant. It doesn't sound as though a further talk will help IMHO.
Forgive me not reading right back through your sitch, but has your W been involved in an A since last March? And you've had an in-house S since then? If so, that's a long time, and boy that can't have been easy.
You say your W has walked all over your boundaries. How did you respond to that? It sounds to me as though she is able to continue her A with few consequences. Yes, you are sleeping in another part of the house - but basically family life continues as usual. Where's the motivation to change this - the reality check?
I would take the focus off her and put it on you. Given where things are at right now - what do you want to do for yourself to make your life better?
