Exh input goes from 'you need to keep me up to date on every minuscule thing in DC lives or you're being purposefully obstructive' to forgetting that he's having them and not turning up until I call and remind him. Either way it's never his fault always mine.
Only DD11 sees him now and he's flakier than ever now he's in a new relationship. Saw her for 2 hours over the entire Christmas school holidays and festive period. And then he wonders why when he does call and want to engage she's not interested.
He's never paid a penny in CM in all the time we've been separated. I used to bring it up a lot initially but he called me money grabbing blah blah blah lambasted me to everyone we knew saying I saw DC as free income, and bizarrely they agreed with him 
So yeah. I stopped bothering with that and have supported them myself 100% since we separated years ago. On the VERY rare occasion he's bought something (new pair of boots or school coat), he doesn't let anyone forget it, certainly not DC. It's rolled out every time he feels badly done to.. 'and after I just bought you some new boots...'
Last month DD11 came home early from his in tears, told me he'd made her feel bad that he'd bought food in for her tea, like feeding her is special treatment. He'd said 'I bought sausages in and cooked your dinner and this is the thanks I get?' (because she wanted to continue playing on the Xbox and he wanted to check his fifa cards or some such nonsense.) DD told me she'd said that he kinda has to feed her because that's just standard and that's why he'd brought her home early. He's also threatened to not see her again/take her home early if she doesn't 'behave'. I had MASSIVE words with him about using visitation as a weapon and holding it over her.
There's SO much more but I don't want to out myself.
To the outside world he's a devoted dad, very present in their lives. But we all know that's bullshit.
