Instead of blocking, try waiting before responding. Our WAS's have a great way of making things sound urgent, getting us ramped up emotionally, etc. When she reaches out, try committing to some period of time (a few hours?) before taking any action. Post here if you need advice in the meantime. I turned off previews on my phone, so if I see my W texted me, I don't see the content until I unlock my phone. I will intentionally not check the content of the message for awhile (assuming I know it cannot be anything urgent).
Example of the kind of bait you might get:
"How are we going to get through this if you don't respond to me?" "You aren't showing me any respect by going silent." "I'm really upset and I want to work this out with you. Please! I can't deal with this!"
Do you need to respond to any of that? No. Will it get your emotions stirred up? Absolutely.
Good catch on idle chit-chat. It is often a way to just make sure you are there and responding.
