I think the fact that he lost his memory and only 'lived' through what he did to her by reading his diary, he doesn't fully understand the severity of his actions, thus thinks he can fix it. Not to mention he's technically younger so his methods will not only NOT work, but are more 'childish' by nature. As of now he technically never lost Navier, his child, and probably has no memory of Rashta. I'm not a fan of the memory loss trope, but I think him acting like this makes sense. He's just gonna have to get told off on multiple occasions for him to gain some sense, but I don't see that happening anytime soon.
