This little speech she likes to give about "we're both good people" I want to object to. I'm a good person. Not so sure about her.
If that is what you think then let her know it. "You are not making good choices and your behavior is destructive to the family. It is causing obvious stress and turmoil in the boys. I don't agree with your comment that you are a good person, a good person would be aware of how their behavior affects others. And your behavior is negatively affecting the boys and myself."
Make your case around the behavior that bothers you and you see impacting your kids. I am sure seeing your boys like this is hard. Sending up a prayer for you and your boys.
Cheers
