I think that you have the right idea with letting the call go voicemail for self protection. It takes a non-disordered person time to heal from these wounds.
^^this is why no contact is so essential
it allows us to see things for what they really are. we are so bamboozled with their chaos and overreactions that we lose sight of ourselves and reality... .
keep your distance and heal... .bring peace and predictability back into your life on a consistent basis, and before long you'll realize the quicksand you were standing in before
