STBX does pay for D17's phone - it is literally the ONLY thing he pays for. He owns a phone company though, so no big deal there!
I'm trying to keep the perspective that he is just lashing out from fear - fear of losing his kids, fear of going broke, fear of his whole world crashing, fear of death...
Trying to convince D17 to sit still and wait for him to calm down before fuelling his rage any more. Not working on a 17yo who WANTS HER PHONE!
