If you can just stop loving her then you never really loved her at all. Love doesn’t work that way. If you ever truly love someone, then it never goes away. It can become something else. There are all different sorts of love. It can even become hate—a thin line and all that—and, really, hate is just another kind of caring.
You are personally responsible for becoming more ethical than the society you grew up in.
Please don’t tell girls “The boy who’s picking on you actually just likes you”
Even if it’s true, you shouldn’t teach girls to respect that sort of affection.
And you should definitely not teach boys that expressing their attraction to women through violence and disrespect is ok.
