They say to keep your friends close and your enemies closer, but what about the idea of having no enemies at all? If you know someone who hates you, it's probably because you two had some type of blowout or disagreement that hurt the other person deeply. While you might not be able to get your friendship back to its old glory, it is possible to mend fences and get your old friend to like you again.
Find out why the person hates you. Hate is a very strong word, so it's likely there's a good reason for his feelings. If he won't talk to you directly about the problem, try to ask one of his family members or close friends about his feelings.
Apologize for any wrongdoing on your part, even if he wronged you also, according to "Reader's Digest." Take responsibility for the way your actions or words have effected this person and be sincere. Explain yourself without making excuses and clear up any misunderstandings or miscommunication.
Make things right if at all possible. Examine the situation and all the people involved to determine if there's anything you still need to do to make everything right or at least better.
Talk about how your friendship was before the event that caused things to turn bad. For you to effect someone so badly that he now hates you, it's likely he previously trusted you or thought highly of you before you let him down. Affirm your commitment to restoring the friendship.
Walk away if all of your best efforts haven't cracked his heart open. Sometimes hurt or anger runs deep and it takes time for a person to heal from that pain according to "Psychology Today." He may just need more time before he's able to come around and be your friend again.
