Hi, I'm new on here but am in need of some advice please. My ex husband has started to blind copy our 12 year old daughter into our emails. Our relationship has been very fraught as he was always used to getting his own way during our 11 year marriage. I have become much more assertive and forthcoming since he left me and I know he hates this and being told what to do. He has blind copied her into heated discussions/ arguments to do with financing a school trip she is going on. I know this because I asked her (had a sneaky suspicion as he's done this sort of thing before.) I am worried about what he says to her and my other daughter when he is with them. He has encouraged them to lie before. I have a great relationship with both my daughters. I have confronted him and tried to nip it in the bud but he won't talk to me. What can I do about it as this seems beyond my control. Any ideas would be gratefully received.
