If your husband cheated on you, could you forgive him?

“I found out my husband slept with one of his co-workers a month before we got married. We’ve been married now for 5 years and he says it was a one time mistake because he was feeling panicked before our wedding. I’m heartbroken, but it was five years ago.
Do I forgive him?”
