Ex has kids (11 & 7) once in week and EOW. He has been living with new(ish) GF since March and so they now see her when with him. He was an average parent before this relationship and while we're not particularly amicable things ticked along ok. Now though, he quizzes the kids on what they've eaten, what they've done, how much fresh air/exercise/sleep etc. I receive a text every couple of weeks about things I've done 'wrong' and how the new GF is so caring and spots these things when she's not even their mother.
Lockdown has been very difficult, I'm working FT and one DC has behavioural difficulties (awaiting assessment). I've asked him to help having DC off just a couple of extra hours on his day, he refused. He picks up after 5pm and drops off at 9am so I have them the whole day while working.
I have asked him to stop messaging as generally I can counter every one of his claims and I obviously have my own comments on his parenting style. I don't raise these with him as he is controlling and manipulative. I had to go grey rock with him at the end of our relationship so replying to him is not productive as he wants the attention and to provoke an argument. The kids ask me why he asks so many questions, he asks them to explain themselves over and over and then they trip over their answers and sometimes give any answer just to stop him from badgering them.
I don't know what to do anymore - I don't want him contacting me, don't want to reply to him, but don't want him to make accusations and me not be able to refute them. I've considered taking him to Court to set up a more formal parenting arrangement.
Has anyone else experienced this?
