How to get my husband on my side react to Ruby as ???(read desc. for more details)

AU: Ruby has enough of the mistreatment she was given. This led her to perform a ritual for her soul to transmigrate to a new body. Now she was reborn as Durandal(aka real Kiana), reborn into a loving and caring family. The love she felt was short-lived during the second eruption. Now she comes to face a clone whom she thought of as the baby sister she never had. And she’s determined to make a new change and leave the past. As she embraces her new life as schicksal’s strongest valkyrie. And embracing her new identity as Durandal/Bianka.
