Here's my thought on this scenerio. At the beginning, yes ring stays on but if the bull becomes either a primary lover and bf, I like the idea of him telling her to remove her rings. When she is with him, she belongs to him in every way. They become a couple and are represented that way. I also like the idea that at some point he puts a ring on her finger and told when it's in her finger she is his fiance until the ring is removed. The husband has no rights until it is removed and she puts her wedding rings back on.
