Thanks for your excellent post. This was just what I needed to hear now too.
The thought occurred to me after reading your response that if Mr. Rabbit pushed back after interacting with LR's family it would be really easy for him to transfer ALL of his guilt/anger to Ms. Rabbit if she inserts herself into this situation by contacting him. He will have to be alone with his thoughts if Ms. Rabbit keeps quiet. Just my 2 cents as we say in this part of the world.
