Shalom Rabbi, say a person does something morally wrong, feels remorse, and then tried to ask for forgiveness only for people to not forgive the person and to turn their backs on them. What should the person in this situation do?

ב"ה Shalom and Moadim lesimcha The Rambam= Maimonides is the Laws of Repentance 2:9 writes that a person is only forgiven for an offense to a colleague when one asks of that person forgiveness. If this person does not desire to forgive him, he should bring a group of three of his friends and approach him with them and they ask for forgiveness on his behalf. If the person does not offer his forgiveness, he should repeat the above process an additional two times. If after these additional two attempts, he does not grant forgiveness, he dismisses this person and needs not pursue the matter, and the person who did not forgive is considered the sinner. In section 10 of the same chapter, the Rambam continues by saying that : It is forbidden for a person to be cruel and refuse to be appeased. Rather, he should be easily pacified, but hard to anger. When the person who wronged him asks for forgiveness, he should forgive him with a complete heart and a willing spirit. Even if he aggravated and wronged him severely, he should not seek revenge or bear a grudge. This is the path of the seed of Israel and their upright spirit. All the best
