First, you have been handling things perfectly. You are amazing. You don't even know.
Your x a$$hat and my a$$hat should get together and talk about how nothing is their fault ever, and that they should have zero consequences for what-errr-the-he!!-they-wanna do. Couple of nine year olds. Tthhpppllllttt.
Crazy how xh doesn't acknowledge he is the one who caused this. Every bit of it. Only he did. Yet, he "can't believe you told S17"... Because he should not have to have a consequence of bad choices???
I'm proud of you. I hope you have a fantastic weekend!!!! I'll be thinking of you!!!!
