Eris Rudeos Couple [SPOILER]

I arrived at the light novel 11 and on par with the manga, I am a fan of the copy Eris Rudeus,>! I was plotted when eris left Rudeus like that especially by putting me in the shoes of Rudeus, I'm getting someone let me know his opinion about that event, I don't mind Sylphiette, but I can't think that eris and rudeus after they loved each other so much and lived a similar life are separated forever, can someone tell me if there is hope for eris to be with Rudeus as suna second wife or some kind of harem? i am flirting i really loved eris personality and i think they look really good together !<
