DP's ex-g is a piece of work. She delights in sending vile messages about how he is letting the dcs down and is a crap parent, all the time refusing him access and taking 1/3 more maintainence BC the dcs need designer clothes in her opinion (not exaggerating at all btw 🙄).
I am trying to keep my distance but it sends him into a pit of despair when she says such unpleasant (and untrue) words.
