About forgiveness 💔

I used to have a friend who was very close to me. Later, she really let me down in some matters, even deceived and betrayed me. I thought about learning to forgive her and took the initiative to reconcile. However, the other party completely doesn't think they have a problem and has a very arrogant attitude. This makes me very angry, but I'm also struggling with it. On one hand, I think about how good we used to be; on the other hand, I recall her arrogant attitude. Part of me wants to forgive, while another part doesn't want to, leaving me in a dilemma. Every time I try to forgive, I remember her hard-heartedness and feel discouraged again.
