Hi! You know, to give you the best answer, I think I should ask you a few questions first that will help define the problem and the situation.
It might be true that you have to stop having contact but let's first get a little more clarity on the situation, okay?
When was the last time she made the statement? How often has she said it in total?
Does she say she loathes you? What does she say?
What did she mean by asking, "Have you never said things you didn't mean?"
And what did you mean that she said it in a toxic way?
Any extra information that will help, feel free to share.
Let's go forward from the answers to these questions.
Please go ahead and post your response. I may be away from the computer for the night before you respond. If so, would tomorrow be okay for me to respond?
