Good for you, itm, telling H like it is re him wanting you to tell him how to D you. Oh the things those little alien minds think.
Don't sign anything without your L seeing it, to protect yours and your boys best interests. He is not going to come out of this unscathed like he somehow feels he will.
About your anger getting the best of you, that's why it's usually advised to detach from the situation, and don't talk R talk with them. When you see him tomorrow, keep things light, if you can, and tell him when he starts in on you, that you would rather not talk about that right then. And change the subject. Talk about your motorcycle or something he is interested in, like the boys. You've told him you don't want a D, so he knows this. Just try not to let him bait you into getting angry.
