I tried giving my crush notes, but he didn't respect me. I want him to like me! What should I do?

It's not what you want to hear, but you shouldn't pursue this crush. This person doesn't respect you. Him having a crush on you wouldn't suddenly make him respect you, and you can't fix someone's problems or make them a different person, even if they do like you back. Getting in a relationship with someone who doesn't respect you can lead to you growing resentful at best, and the relationship becoming abusive at worst. It would be in your better interest to get over this crush. Remember, as much as you may like him, you deserve someone who will respect you unconditionally, and anyone who says otherwise is wrong.
