Separated from H at the start of the year. There is back story here (he was SAHP who left for OW and despite trying to keep up contact etc, he feels i have been unreasonable & now only sees DC every other Saturday night - his choice!)
DC are with a childminder whilst i work FT and yesterday DD fell over on her walk home and turns out she's broken her arm 
Have spoken to the childminder and she's going to report to ofsted. DD spoke to H after we were done at a&e and told him she wasn't with me. I know he'll be angry, because he always is with any decision i make around the DC and care for them.
I am really scared he's going to.use this against me in mediation which we start in a couple of weeks as a way to take my DC; I'm not able to care for them or arrange suitable cover sort of thing & they'll be better with him. He's still unemployed so has the time which i don't as i work 
Am just gutted that DD is hurt and now scared it will be used as a stick to beat me - even though i wasn't even there!
