Reading the boards .. and your sitch .. seems lately we are all struggling with the R between our WAS and our children. I at times have been in the same boat ... but what can we do really ... there is no forcing the crazed MLCrs into being sane around the children, I have just accepted I can not control the R between my S and my W. And you are right .. any judgement/advice we give is typically wrapped up and hand delivered back to us in a spiteful .. "Its actually your fault" type response ... (I have even been given its her own mothers fault as well)
So ... what can we do ... exactly what we are doing .. be that beacon, lighthouse, rock .. whatever it is ... what my S does not get from the WAW I pray he will get from me, see the way I handle and conduct myself and hope he mirrors me and does not ever think its right what his MLC does ... I also do not want him resenting her.
