A little context. I am a single, full-time working mother of 3 girls. My daughters stay with their dad every other weekend. He was a cheat and our marriage ended over a decade ago. He has always been snippy in his communications with me. I endeavour to ignore, as engaging with him isn't worth it. He'll never change and it is no good for my mental well-being.
He is an extremely high earner and I'm not. He makes it clear to me that I am a millstone around his neck, even though I'm a good mum to our 3 kids and do pretty much all of the nitty gritty parenting. He is unsupportive of me and an arrogant individual. Believe me, I have tried my best to keep things amicable.
Our youngest (nearly 15) is showing signs of becoming a school refuser. I am worried sick and doing everything I can.
This morning, I got her up as normal and was cajoling her along. I then had to leave for work but had a bad feeling that she may not go in. I emailed my ex husband and asked if he'd please check in with her, by call or text (as would I, as it's not like I have the luxury of simply forgetting!).
This was the reply I received. I actually don't feel like I can ignore it. I need to say something, even if it will fall on deaf ears. This man is ALWAYS right. The basic message is, 'I pay you maintenance so that I can opt out of these things and focus on my big career, so put up and shut up'.
Please don't judge me. I have had enough of dealing with everything on my own.
And if you are kind enough to help with a reply, it needs to be concise and with as little emotion as possible. Emotion annoys him and he doesn't take it seriously.
He's an arsehole, right? 
Oh, and the point about blaming the dentist is nonsense. When he asked me if the girls had been to the dentist recently, I replied 'oh yeah, they must be due to go, but I don't remember receiving a reminder, so I'll check it out'.
