Thanks for the thoughts, everyone. Appreciate the perspective.
WAW moves out on Friday. We have MC tomorrow, where I think I will bring up that I don't believe MC will be helpful while we are separated as we both need time and space to process, heal, and grow.
We also have time carved out on Wednesday to go through our finances together. Her current position is that I should help her with a chunk of the rent of the new place, and that we should maintain the current status of a shared bank account, and shared cards that we use for things. I don't have much of an opinion on the former, but on the latter I feel it is obvious that if we are to separate effectively, we have to separate financially as well.
Beyond that, plan is the same. Minimal contact now, only when she initiates it. Always leave the conversation first. No pleading, begging, or emotion. No discussing the R. After Friday, no contact.
In the safe space of this forum, I will admit to being scared. And hurt. But I know what I have to do.
