Ah, my husband also does that when he’s mad. He’ll ignore me. He won’t even look at me. There have been times when I’ve actually cried in front of him, and he just ignored it. He just played on his phone like I didn’t exist. It made me feel less than human. I’m sorry that happened to you.
The country I live in has “ignoring” listed as emotional abuse. I don’t know about the country where you live.
I’m sorry you’re being hurt. I understand the pain of not being spoken to. I send you hugs, from my country to where-ever you are in the world.
