My first question is what is hubby doing about it. But I received some really good advice when I was having trouble similar to what you are going through. My daughter was in counseling and the parents of this particular group had their own group. The counselor told us 2 really good things that I walked away with. One was to pick the mountains you want to die on. In other words, determine which things are important enough for you to really stand for. The other is that teenagers are terrorists and will take you captive if you let them. Never argue with them as that is their method of taking you captive. When I learned not to engage in her argument because I did not have to as I was the mom, things got better. She is grown and a beautiful person. Like you I am in my 40s, but I have 3 daughters. So I can feel where you are coming from.
