For her part, she is fully into blaming me for every bad feeling she ever had over the last 25 years and still refuses to accept any part in our marriage troubles. She just doesn't feel the same, can't help that, it's either there or it's not.

My h blamed for a traffic jam. Broke down sobbing saying it was my fault that traffic was bad and that I caused this on purpose because I knew he would be hungry. Really. He did. Detach. Stop worrying about why she says certain things or behaves a certain way. You cannot control it.
In regards to D14, I think you should approach her to ask her how she is feeling or if there is anything she would like to talk about. That is a difficult age. My s11 and d9 see a therapist and it is really helping. Like Wonka suggested, even chatting with the school counselor (I advised the counselor of changes at home too) could prove beneficial. I'm not sure if you have an religious or spiritual affiliation, but speaking with a chaplain, pastor, advisor, etc may also help your d.
Let your w go. She has to work on her stuff. Yes, it's difficult to explain the unexplainable. I love karaoke! Have fun. Stop focusing on FIL and W. Focus on you and the girls.
