Being cut off?

Hi all... I’m not actually sure if my ex daughter in law is cutting me off surreptitiously!!... I’m not mad on social media but do look at it to keep up with my GS etc. Recently what used to be a constant stream of daily posts from her have disappeared!!... also she never answers my FaceTime calls always either txt an excuse or just ignoring me completely.
To my face she is all smiles!
Btw, the divorce has just been finalised and is pretty amicable so I’m a bit surprised but maybe naive?
