Shows her ambiguity = or perhaps her guilt? Who knows. I think you are spot on to take some solitude and not respond. LRT = going dark. She has to live with her decision now.
Or, you could look at it as, hey, at least she is respecting your love for your children by sending you pictures?
I took a few days in the mountains with my S5 this week and the solitude got me really grounded for whatever comes. I am more detached than ever. I got rejuvenated and reconnected with my inner strength. Being surrounded by nature (I was also by a serene lake) reminded me of god's love and I just kept repeating "Thine will, not mine, be done."
Hope you also get some peace and inner strength during your time away.
