Google some videos on transactional analysis. Unfortunately, your ex can’t stay in healthy adult mode for your interactions. Her deleting photos you haven’t liked is just pure manipulation - cue child state.
Don’t interact, don’t respond... and understand that people who do this have deeply ingrained issues and most likely will never change.
She can be as pissed as she wants. That’s her problem, not yours.
If we had a "like" option, I'd use it for this post.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
