Luke, are you still seeing an IC? I think this is a good problem to bring there for constructive advice.
Your daughter has in a way become like your W in your mind. You seem to have gravitated away from her as she has gravitated toward her mom. You seem reluctant to claim your natural place as her dad, for fear of something undefined. Your wife may be a lost cause but your 15yo daughter is not, and your IC can give you specific homework to try to salvage this relationship. I hope you do.
