This happened with my husband and me (29 year marriage)
I felt I walked on eggshells too. I finally told him 6 months ago that I needed to be alone.
He moved out but hasn’t given me peace since that time. His pleading has pushed me farther away.
He tells me he can’t live without me and that he isn’t going to make it and this makes me so sad.
I cannot do anything about it because I don’t love him and cannot live with him.
So if I were you, I would give her space and let her have her time alone. If she loves you she will come back to you.
I wish you well. I know this hurts so much.
