Told H boundaries had to be set and to not talk to 'her' around S. I said it does not set a good example for S. H shook his head, sighed, and said "Whatever!" Now he's acting like a 3 year old in a temper tantrum, making sure he does not "brush" me as we walked past each other, shutting doors forcefully etc...

Okay, my dear friends, did I make a mistake in what I said?
