If there are multiple endings, I think there's a bug in what endings are shown. I've tried swapping choices on multiple characters changing the attitude ranging from "Indifferent" to "Adores" now and only ever gotten one ending for each character regardless of the attitude.
Also around the relationship status not showing, I think it has to do when you make good choices when you are already at the "Adores you" stage. If you are at that stage and select more good choices the status will just be blank.
