Namechanged.
XP and I separated around 7 years ago, we have a 9yo DD. It was not an amicable split and his entire family, especially his dm, made my life rather unbearable. We ended up in Court which resulted in shared care of DD, completely equal, we were both considered to be adequate parents. A couple of years ago, we ended up in Court again - horrible experience which resulted in dd living with me and staying with her dad a couple of nights a week. This obviously didn't go down well with xp and his mother who had made countless referrals to SS about me (all malicious, unfounded and no action taken). However, we had reached the point of being civil, if not friendly, to one another. Until dd returned from a holiday with them. Apparently ex-mil has told her, out of the blue and amongst some other vile stuff, that I didn't want her when she was a baby and that she was taken away from me to live with her dad. It's so untrue and unfair, I feel like banging my head against a wall. I can't confront her because it would make things unpleasant for dd. I don't feel as though I can cope with this crap on and off for the rest of my life. What would you do?
