He apologized and then went on a rant about how difficult a time he's having. Absolutely no concern about what my son is going through, it's all about him. I'm going to need stitches from biting my tongue... I'm going to try not to react to his threats or feed his need for attention. Hopefully eventually he'll learn that I'm going to ignore his tantrums, and won't respond to him unless he is being sensible and respectful. It's going to be super irritating. I will research the legal process just in case.
