I have kept mine on, but have considered taking it off. H took his off (and kept it off) the first time he went to visit OW. The first time I walked into his office when he wasn't wearing it, he went to great lengths to hide his hand from me.
I have kept mine on so far because I am still married. I also know that my daughters will notice if I take mine off. They have not mentioned their dad's ring to me and would never to him...but I know they will notice with me. When I do remove the ring, I need to be prepared for their questions.
I feel the same way as someone else who posted here - is it desperate looking? Does it appear that I am clinging?
But then I "get still". And I remind myself that this is my decision and that I should do what I want when I want. I tell myself that my ring comes off when I am done. I am getting close, but I am not there yet.
I do not wear any other jewelry H gave to me, including a diamond ring given to me on a past anniversary to replace my engagement ring. If we end up divorced, I can't imagine ever wearing any of that again. For me, it doesn't feel right.
There is no right or wrong answer. It is a personal choice.
