Out of curiosity, why don't you feel you can share photos of the kids with your W? Has she told you she doesn't want them?
I personally don't see that as pursuit, especially if you used to do that before.
Even during our darkest days, my XH and I have done it. For some reason, the kids gave us the strength to work on communicating better with each other. For me, they were tangible proof that this journey was worth the effort. I can't speak 100% for him, but he loves his daughters and appreciated me sharing stuff with him. We still do it to this day.
But you're a better judge of what's okay and what isn't.
