Idk... He made a huge mistake, but he's working really hard to try and change his ways... At what point is it enough that it will be forgivable, and even if it's forgiven, will she still be interested in loving him? Rn, it seems that she's never truly let go of her feelings, they're just covered by hurt, but I also wonder if it's fair if he's forgiven, since that wouldn't usually happen in reality. Sometimes people are depressed and their spouses suffer from it, and by the time they pull themselves out of their funk it's too late... The other party has put in so much and has finally given up and they have no reason or responsibility to put more into the relationship. They are completely in the right if they leave... But since this is a story, I hope the redemption arc is true and he truly redeems himself instead of just being like "I love you and have always loved you but I only just realized it so let's get married again, ignoring all the pain I put you through bc I said I was sorry."
