This might be a prank or joke but I appreciate that they talked about it and that he's willing to work things out. He even said that in the future should she feel tired of their relationship, she needs to tell him in order for them to fix it than easily give up on each other unlike other couples who do dumb things like find excitement on other people and ruin further their relationship. He humbled himself and acknowledged the possibility of trouble in their relationship and he is willing to work things out for both of them.
