I expect the fall-out to be the same with my mother. Maybe not screaming and ranting, but the silent treatment and the heavy sighs to alert me to her displeasure. God I hate that manipulative BS! My dad isn't giving me a hard time, though. He's usually good about stuff like that.
I'm so sorry you're having to deal with this. I really am. However, I must agree with my predecessors on this thread that you do NOT have to take that abuse just because she is your mother. I've resolved not to let anyone abuse me anymore, over the telephone or otherwise. I respect myself far too much now to allow it. Just because you don't want to be in a cult does not make you worthy of abuse. Unfortunately, when you are dealing with people who can't think for themselves, you have to just let them think what they want. It hurts to know your own family thinks of you that way, I know. I've been told I'm on Satan's side, I'm a dangerous demon, I'm a tool of Satan... Those words would really mean something if I believed in the devil, but the spirit behind the words is the actual insult.
Know that you are NOT what they think you are. The only people who think you are horrible are deluded into thinking everyone but them is horrible, too. Which means 99% of the world is in the same boat as you... I'd rather be among the 99% in the lifeboats than the 1% on the sinking ship.
