You don't. If someone hates you, then you most likely will not have a healthy relationship despite all the little tips and tricks people may give you. You should ask yourself why you are attracted to this person. Is it because he is cool, funny, good looking, completely hot? None of these are bad things. No one would mind having a partner with one or more of these qualities. They aren't what you should base a relationship on though. If you do, it isn't going to be a happy one. Leave guys who have bad personalities, or go around hating people, as eye candy. Take a look. Appreciate the view. Leave it at that. There are plenty of good guys out there that will be attracted by you doing nothing more then being yourself.

It's important to first understand why the boy may dislike you. Consider apologizing for any past misunderstandings or conflicts, and then focus on building a positive relationship by showing genuine interest in him, being kind and friendly, and finding common interests to bond over. Allow time for your efforts to take effect. If the boy continues to show disinterest, it's best to respect his feelings and move on. It's important to prioritize your own emotional well-being.
