My strongest boundary applies to all my relationships, although it was formed during the dysfunctional chaos with my son's addiction. It is this...
I deserve respect, in action and words. The moment a conversation becomes heated, angry, sarcastic or disrespectful in any way...it is over. I will walk away, hang up the phone, remove myself from your presence. I will talk all night if need be, as long as the conversation remains respectful. I will give the same respect to you as I expect for myself and accept nothing less than honour.
My boundaries are about what I am willing to accept in my life and what I am not, and the actions I will take to apply them. If you choose to have a relationship with me, respect and honesty are the two most important requirements, anything less is unhealthy for me.
