Hello Azzork, I think the answer to your question is to decouple the behavior she is exhibiting towards me with possible outcomes from her working through her struggles.
I am equating her cold indifference and silence with divorcing me. Thank you Azzork, you are wise. I think I have a new goal.
Her cold, indifferent silence is about her. It is not about you.
While it hurts to watch, you cant let it tear down the person you are.
