Apologies, but here's a 2X4. Your wife is very likely STILL an untreated, unrecovered, mostly unrepentant alcoholic who is hiding the full extent of her drinking. 2X4: Your wife would lie about this because she has already proven that she lies for long periods of time about alcohol and infidelity (and perhaps more).
You said:
Is there any value in confronting my W with my knowledge of her lies?
Is it better for me just to ignore this completely?
What is the best strategy to get her out of the house sooner?
Why would you ignore this completely? Because you want to work on your M? You can still work on your M if you put her out.
Go to the infidelity thread later and see what they suggest.
It doesn't seem good for your mental health (and thus not good for your children's mental health) to be lied to and cheated on under your own roof.
If you decide to get her out of house quicker, just tell her you have proof she's been cheating but don't share it with her. Say that's the reason she has to move quickly and give her a few days to go.
You don't have to help her in any other way. She did this, not you. If you decide to do this, you have to release yourself from enabling her not to experience the consequences of her infidelity.
If she can get a room at the Ritz to have an affair, she can quickly get a cheap motel and then rent an apartment. Not your problem. Sorry to sound harsh, but if and when you decide that, it's true. You have the right not to be abused in this way even though you may not have been the perfect husband.
