True....but also, relationships aren't one-sided. It takes two to make a relationship. If one's needs aren't getting met, I.E how the girlfriend wasn't expressing enough love in the relationship and made it seem like she was the one who wasn't interested. Like even I would be complicated and wondering if she truly cared about me if I was in the male characters shoes. And yeah for the other girl, he should've taken her feelings head on and if he didn't want to have that kind of relationship, he should've told her straight up that his feelings weren't that way and he only wanted a family relationship only instead of leaving something for her to cling onto.
I just had a feeling that that sly villain would just pop up "so suddenly". Seriously though...Just...stop. Move on with your life.
