can a relationship be saved after cheating? ( both perspectives)

what are your opinions or any personal experiences that you can possibly share about this. Can the love be brought back or no? What are your thoughts?

If the person knows what they did was a mistake and wants to prove to you change, is it worth saving the relationship? How do you rebuild the trust ?

( both perspectives would be helpful if you once cheated or you were the person cheated on)

Please share! I really want to know.
