LW this post kind of bums me out as it has your S going against his Mom this kind of thing will only grow into greater resentment from him to her. NO matter what happens between you and W they need to have a loving relationship and connection for life. I feel like you rewarded him for this kind of behavior which is not good behavior. This creates a bad dynamic of teaming up on W. I am speaking from experience here this is the type of stuff my dad would do when my parents split up and 30 years later I am in therapy to repair the relationship with my mom because of the seed of deceit he planted when I was young.
