Does anyone have any ideas regarding taking the possibly unorthodox approach of calling the ex out and outlining the damage she is doing to the children in her attempts to control DH?
In our case, using the direct approach has only resulted in the entrenched position of "my children don't need therapy" - not only reiterated to DH, but to the school (who recommended play therapy for DSS) the family GP (who suggested a CAHMS referral), and the social worker assigned to DSS case. She also cited in court that DHs desire to seek therapy for the DCs was abusive.
But, DH did send DSD a copy of the Warshaks DVD when she was last no contact with us - knowing full well that Ex would open it, and view the DVD, in order to find more material to support the alienation. He obligingly wrote a covering letter to DSD explaining what the DVD was, and how DSS had seen it too. Not sure if it made a difference, or not.
I know that her approach has changed since she applied to court and attended (court ordered) the SPIP course - she has, finally, realised that she can't rely on professionals and the family courts to automatically enforce her will on DH. So, whereas this time last year, she phoned/emailed DH a diatribe of abusive vitriol because he refused to sign over DSD investments into her (exW) sole name, this year, when the same circumstances arose with DSS investment, she has "accepted" DHs silence on the subject.
DH considered long and hard whether to apply to court for a Specific Issue Order regarding counselling/therapy for DSS - but, the professionals he spoke to made clear that unless DSS's mum was supportive, then it wouldn't be beneficial to him. She did, fairly soon after I'd moved in with DH, agree to a short set of counselling sessions for DSS after he became distressed about things his mum was saying about me and she eventually admitted that he'd "overheard" DSD and her slagging me off - the alternative was to agree that DSS must be lying.
The Counsellor gave up after three sessions as ex was openly coaching DSS while they were in the waiting room. The counsellor was incredibly apologetic to DH, and tried to highlight the damage being done to DSS to exW, but exW knew better.
