If you hate someone, you cannot have peace in God. Because He is the one who said: “For if you forgive men their trespasses, your heavenly Father will also forgive you (Matthew 6, 14).” And if the other person is not making peace with you, you always keep yourself away from hate, and pray for him honestly and never say a bad thing to anyone else about him.
