How to not be annoying to your crush
Avoid being clingy.
Although you may want his attention, it's important to give him his space. If he feels that you respect him and his personal space, he may be more likely to interact with you.
Otherwise, he may view you as a needy person and stay away from you. For instance, if he doesn't respond to your text within five minutes, understand that he has his own life.
