I think it is time to go dark. Regardless of what your W does, or says, you have to just ignore it and not let it get to you.
Mate, I went through the same, the lies and deceipt, and it nearly turned me into a fruit loop. My W even had the OM to our house when I was away for work, and driving my car..........so you can just imagine how angry I was.
I set my boundary's with her several months back, and what she does with him is her business, but keep it away from my personal space (home and car included).
She still has my DD included in their activities, which I don't mind. Kids are smarter than you think. My DD tells me that OM has not bought her or treated her to anything since they have been together (he is 27, W is 36, so his priorities are different to hers). He is a tight arse with his money, and W pays her own way with every activity (I may be old fashioned, but doesn't the guy pay during courting???? Especially if there is a PA).
I have gone lovingly dark, the best way I can. She has instigated all calls, and I am being as civil as possible for DD's sake, and as polite as pie when it comes to dealing with W (without being a doormat).
So yes, I think the way your W is acting, you should go dark, but civil.
