I think it's fine to know that this kind of contact doesn't work for you just now and take steps to avoid it. I don't know about the technology, but I always think it's worth making it work for you.
Alongside doing this (for you) I would encourage you to hold as much compassion as you are able in your heart for her. Maybe it's because we had a session on forgiveness at our divorce group recently, but do try and release her peacefully to live her life in whichever way she chooses.
Take care Irish (& pink shirt sounds very nice by the way) xx
