I have to agree 
with what Copa is saying, he is bargaining. Definitely his conduct should be how you react to the situation. I can only imagine your dear heart screaming ….what if he is serious and will change? All these years I myself put on those blinders of her having severe mental issues. But while yes, they do suffer from my daughter is a functioning, capable, manipulative person. I saw this clearly last year she lived with us. She held a job for 3 years, saved 10 thousand dollars on a down payment for a new car. Life was not perfect, we walked on eggshells around our house fearing her next verbal attack but, she was functioning! She knew what to say and the manipulation with everyone was clear as day….except to myself. 
When she left was my awakening, she chose to leave we did not kick her out. If she had shown me she was taking positive steps to keep on that path as she was of holding a job we still would be working with her. So happens after she had gotten a car old ways came right back. Getting on the dating apps and meeting strange people for sex. She was spending every penny she earned, she brought pot into my house and $300. worth of sex toys to be with someone that weekend. It all fell yet again. So here is where the commitment from them comes in and so sad to say, he is not showing it.
