Kairo haven't moved on from his ex. He misses her. He wants to forget her by dating you. But once you both got married, it got worse. He keeps comparing you to his ex, and he doesn't care about your feelings. All he does his compare you, and ignore you all year! It got worse once you both got married. I don't even know if he care and love you. If you gone missing i'm sure he wouldn't care. You remind him of her. And just made you his distraction.
