I don't remember reading anyone on your thread suggesting that your W moving back was going to be "easy"...
This is going to take more resolve and patience than you thought you had, but I have every confidence that you can do it.
Your W has moved back in for what ever reason and for however long she expects or ultimately can endure.
In the mean time, I do see a lot of expectations in your actions. You are not just going about your day as though you have a temporary guest. I see you working on rebuilding a broken M.
Stay away from R talk. Go about your day. What ever she is expecting FROM you, is HER expectations. Don't feel you have to live up to them and don't be baited when she tries to tell you how you are not.
You broke the candle holder, you apologized. Done. She is not letting go of it. She banters you. You take the bait.
As Val said, set your boundaries and get yourself out of the argument as soon as possible. She invited herself back, you opened your door to her, but that does not mean that she can come in and assume she is your partner and you owe her anything.
Still, do try to maintain your serenity and humility and compassion.
Keep moving forward. Do find some GAL so you are not hovering over her or smothering her.
