My W took hers off during the begging stage as well. Ive been conflicted about it.
My S7 found her ring on the night stand and said to me "dad mom will be mad if you don't put your wedding ring on". I told him it wasn't mine and showed him that I was still wearing mine. He then took the ring and ran to find my W. I don't know what was said but he shortly returned and put her ring back where he found it. My W accused me of setting the whole thing up.
I have decided to keep it on for 2 reasons. 1. I think it shows our kids that I have not given up. 2. The fact is I am still a married man whether or not our M is going well right now. In the state im in it would be difficult for me, if by some chance another woman took interest, to stay faithful. I don't think I would act on it because the last thing I want right now is to deal with another female. Also its a constant reminder of my goal.
