My situation with my WAW....

"I am trying so hard to go dark, but she keeps contacting me about our son."

You have a son so you can never go completely dark. Go dim instead and be cordial when you discuss your son.

"She brings me to tears so easily,"

No. You do that to yourself. She isn't doing anything. You control how you feel.

"I feel as though she was just pretending during our marriage,"

You know that's not true.

"the only regret or remorse she has expressed to me is that she married the wrong man."

They all say that. What you need to do is let comments like that not get to you. It's tough, but can be done.
