Ugh...I was not fond of her from the start. She did something I can't remember, and I thought she was a bit fake. You did what you knew was kind for your son. As you said, you wanted to get him out of high school, and you did. Mission accomplished. And you have one less mouth to feed! And he is free at a good time in his life, starting at a new point. I agree, leave the job. She sounds like she may cause him a problem.
