How I see it - because it fits exactly what I've been going through. Two people who had some sort of feelings for each other (could be romantic, or in my case, platonic "besties" but underneath there is an interest by one side). He's coming the point of realizing that they are officially falling apart. But she means so much to him. It had been an amazing friendship. He remembers the good times - painfully. He knows she is going but wants to just hang out and talk one last time. He knows she feels bad about him deep down but he doesn't want her to feel bad. He just wants her to be happy...even if it means pain for him.
