my wife offered to have an open relationship because she's intimately distant and knows that. I told her I would get jealous if she were to be with someone else and it was something I couldn't accept. if she was willing to accept that I could be and she couldn't then it would be fine, but I don't think it would be fair to her to agree to that.

she didn't really give me a clear answer so we just continue our relationship as it has always been.

jealousy is a hell of a way to ruin a good marriage.
