Here's the thing. You can love someone with your entire body and mind and soul and it might not matter. You can be the nicest, most caring, best person ever, and it still might not matter. You can be all of these things and more, but if the person you love doesn't feel the same way about you, you can't make them! It doesn't work that way! It's dumb as fuck but that's the way it is. You can keep trying over and over to make them see how great you are and how perfect you'd be together but it. does not. matter. After a certain amount of time you just have to realize it's not going to work. It will suck. It will hurt. But there's nothing you can do about it. Move on.
