If I had it to do over, I might just consider the long bouts of the silent treatment as a blessing in disguise! However, I know well from experience how painful it can be. Here are some things to avoid when narcissistic mother is giving you the silent treatment:
When someone walks away after you stand up for yourself, and you don't hear from them for days or weeks. That is not normal. In fact, it's abuse. It's emotional neglect, they obviously don't generally care for you... Please understand that's not real love at all… you're not a door mat to be walked on, your a friend, partner or spouse & deserve better treatment.
