If treating me with disrespect is a boundary for me, is walking away a sign of weakness?
To me it depends on how how you handle it.If she starts raising her voice to you and you look her in the eye and with a calm voice and say "W I will not continue to have the conversation with you if you don't lower you voice and communicate with me like an adult". If she refuses to then you can just walk away.
Now if you get angry or upset and run away and lock yourself in the bedroom. That makes you look weak. IMO.
