You are between a rock and a hard place here T. Teens of that age are natural rebel entities. Remember when we had that age. It seems your D’s rebelliousness is focused on W...then you have W’s rebelliousness...
Just be there for your D14. Don’t pressure her too much about having a R with her mother now. Let time calm the waters.
You need to be the lighthouse T. Be proud of that. Sure your D is seeing your light. If anyone else sees it it’s not your matter any more.
