Looking for Advice on if I Can Save My Marriage or Not

My husband recently told me that he cheated on me. He said it was just a one time thing and a complete mistake that will never happen again. I am now looking for advice on can I save my marriage or not. I am having a hard time forgiving him. At the same time, I want to forgive him. I have been looking online to see what other people are saying about similar situations that they have been in. I am also looking for advice from professionals online as well as other women who have gone through this as well.
