I think Ciel is more of a subconscious component than an independent/individual conscience. The fact that Ciel did nothing while Rimuru was unconscious at the end of time/space reinforces this theory. Based on Ciel's time with Rimuru as Great Sage and Wisdom King Raphael, it developed personality traits that were compatible with the host.

I believe that Ciel declares herself as Rimuru's wife because she understands that it would hurt Rimuru to hurt his friends by choosing one over the other. This way, she can assuage his guilt and allow him to avoid that difficult decision.
