Your issues with WW have nothing to do with daughter. Your relationship with D is totally separate. Do NOT use your D to meet your needs to be validated. You are there to be her parent and meet her needs.
She is a teenage girl. Of course she is going to be opinionated, and what you say will be stupid to her. I wouldn't worry about winning her over to your way of thinking.
Like most DB, the trick is to lead with actions, not words.
Instead of telling her that it's wrong to end an M because you 'fall out of love', just act it. Stand by your M. Do it quietly, without telling WW or D (remember WW needs to feel she's lost you at some point). But don't date other women, or make your life revolve around your sitch. GAL, take care of yourself, and set an example. The fact that she's confused means she needs your example more than ever.
Years down the road she'll come to you for R advice, or at least will remember back to how you acted. It will make a difference. THAT's why you're doing it as a parent. And for yourself it's because it's the right thing for a man to do. Not for immediate gratification. If this was about immediate gratification than you're no different than WW.
Bottom line, do what you know the right thing for a man to do is, and let your actions speak for you. You can't force anyone to listen to those actions, but you at least have to act them.
