So I know people say stonewalling is emotional abuse but what’s the the difference between stonewalling and shutting down and not wanting to speak?

If I feel hurt, I shut down and I distance/isolate myself. Should I force myself to talk to the person who hurt me / I’m upset with because if I don’t I’m stonewalling and being abusive? The thing is I’m not trying to punish the other person or hurt them by not speaking to them…I’m just hurt and would rather not talk. I usually always let them know I’ll take space as well….

Help?
