My personal boundary is:
I choose not to be around my ex (OR ANYONE) when he is active in addiction.
I have decided that I love myself TOO MUCH to put myself through the emotional turmoil that comes hand in hand with the addict. I choose serenity.
Do you have any personal boundaries when it comes to being around someone active active in addiction? Did you in the past? Or was it always ok with you that he drinks?
