Hazel's a lot nicer than I am when it comes to her mom so let me try and paint you a picture here - Marie is a narcissistic bitch who for 18 years refused to allow my little sister, Hazel, to be anything more than an extension of herself and a weapon to use to hurt our dad by not allowing him, or me and our older sister, to be a part of her life.
I've watched her agonize over making this decision for months and seen first hand how talking to Marie tears her up emotionally and mentally. This? Is the healthiest decision my sister could have made for herself dealing with that woman.
