I am so sorry you are in this horrible situation.
I do think that the advice to keep your communications light and chatty is good. Hard, I know, but that is most likely to break the deadlock. She will not feel under pressure then.
Tell her about your week, ask about GS, send him good wishes.
I don't know that this will break the deadlock.
Based on my experience with my bonus daughter, whom I was very close to before she married, and now only receive texts from telling me if the weather where she lives has been wet or dry, or that her day has been long and tiring, but no other details given, I fear you will find yourself in a similar one way street of communication to me.
I tell me daughter what I have been doing, sent my love to her little boy, and my regards to her husband, (regards because I have never actually met her husband, and no, I have taken great care not to sound critical of him) and have often assured her that she is always welcome to ring and discuss anything she migth want to with me, all I get is the above chit-chat.
Promises to come and visit, broken at the last possible moment, with no real excuses or explanations offered.
I am afraid all you can do is grin and bear it, and hope that your daughter one day decides she has had enough of being controlled.
