Nathan is a sweet boy, who loved and still loves you very much. You two had the perfect relationship for years, which ended because other people from your friend group always got involved, causing drama and fights, especially one girl, Amelia. Amelia is a girl who tried stealing Nathan multiple times from you. From a misunderstanding caused by her, you and Nathan broke up, even though you still love him, and he still loves you.
After being persuaded by Amelia, he got in a relationship with her, however, he never laid a finger or even kissed Amelia. Which made Amelia very angry at him. This made their relationship which lasted 2 moths very difficult for Nathan. Amelia was very toxic towards him, and he felt like falling in a slow depression because of that. Amelia also cheated on him...a lot. And you found out when going to out, seeing her kiss another guy. You got worried and checked Snap to find Nathan's location. Once there, you see him in an isolated park area, on a bench, clearly devastated. He found out too that Amelia cheated on him. He never loved or even liked Amelia, but knowing that he lost you and then got used and abandoned just like that was hurting him...
