I think easing them from MS is a good idea also. He is their link to what used to be a normal life for them. Whatever MS is or isn't, he is who they know as dad. With DCF involved, hopefully the girls are getting to express their thoughts and fears to a "neutral" party.
I would imagine these two young girls have a lot of questions that hopefully are being answered honestly. My concern is that If they are constantly being told that their dad would never do anything to hurt their mother; that he was not involved in any way blah blah blah, these girls are going to have even greater trust issues.
Needless to say, I would not doubt that MS has told them a lot of untruths about TS family and friends, essentially poisoning the well.
That bothers me as well Zuri. These precious little girls are likely to have quite a bit of input as to who they will evidentially live with.
