AIBU reading my child’s messages?

[ERey2]

My partner and I have not split amicabley and he sends inappropriate texts to our 10yr, referring to me as a witch and involving our child in his (false) accusations of an affair on my behalf.
Am I wrong to read his messages and should I seek advice to prevent my ex using our child this way?

Hell yes you should seek advice

Print screen and send to yourself as proof, this is very bad behaviour and needs to be addressed. He has some serious issues.

Definitely read messages on a youngsters phone, you ex is being nasty.

Op I took my ex to court over very similar. We had split a year previously and DD was 4, so not text messages but talking to her and saying similar things.
I got a court order which forbade him from talking to her about 'adult' things and being negative about me to her.
It helped to some extent and 6 yrs later I still pull him up on things the court order states he shouldn't do.
He also knows I'd haul him back to court if he crossed the line too far

Seriously adults and those messages to their kids?? Definitely keep tabs on those and do what you can to stop them. Your daughter really doesn't need to be dragged into his swamp of negativity. It's a shame he hasn't got the mental maturity to recognise that his point scoring is v damaging to her.

Please may I ask, did you go through solicitors or did you go to the police in the first instance? I’m not sure where to begin. I’ve had a solicitor’s letter sent to him previously and he just used it against me and now I feel that the kids are finally settling, I don’t want them to think I’m starting it all again, they don’t see it as me trying to protect myself from him.

@ERey2 there was police involvement on2 occasions which prompted me Togo to a family law solicitor

You aren't starting anything, make sure you have those messages backed up and get some help asap.
