If someone came to make amends and come to forgive you for stuff done in the past, and you also want forgive them for words

Said (Like they've stuck to you in a way, resonated within you in the past and they played it off as them saying those things as not a big deal...) do you forgive them, to make amends with them and see them as a different or changed person, or can you not come to forgive them because the wieght of what they said over what you said back then (The insults, the downgrading, the anger-fueled overboard shaming/degrading words.) In other words are you a forgiving person? And would you forgive this person and just want to forgive some of those the wrongs and have less vendettas or just past anger/striff/problems or would you not forgive them and just live life past all that stuff? (Btw a real while has passed so yeah)
