How can i push someone through dual destinies?

So i allready finished 1-6 and inv collection and my wife started a bit after me to also play these games. Now she faces the same issue as i faced when i started to play dd. I really went crazy and wanted to drop all of this, and luckily some nice people in this reddit pushd me to play further. Shes not that kinda online persona, so ive to push her, but her arguments for dropping it sound valid and furthermore i also hate these first 2 cases. I am not good in defending things i dont like. Help me, how can i motivate her to keep on playing?
