in order to forgive some1, do we have to not be mad at them too, or just not want them to have a harsh judjement on yom kippur because of it? Also, if we do have to, would this apply if the person frequently dose what i want them to forgive me for, and i suspect that the behavior won’t change muh any time soon? Thanks :-D

There is a difference between selicha (forgiveness) and mechilah (pardon). Selicha is when you completely forgive someone, not being mad at them anymore. Mechila is when you just don’t want them to get punished for it. (even thought we say mechilah for full forgiveness colloquially).

Is someone continues to do the same thing and you already forgave them, Hashem doesn’t forgive him until he changes and you forgive him again.

Hi. thanks for replying
and if the person dose it to me frequently, and i don’t see it changing am i SUPPOSED to forgive them?
and when whem we forgive ppl on yom kippur, are we supposed to have mechilah, or selicah?

The choice is really up to you, but the Torah encourages everyone to try to find it in them to forgive every Jew wholeheartedly (selichah). Try to find a justification, or at least convince yourself that the other person will eventually change.

thank you
