My Boyfriend Cheated

I love him and he loves me. I know he does.. But he cheated on me when times were rough in our relationship. He said he was sorry and that it was a stupid mistake. I know he regrets ever cheating on me and that hes truly sorry. But how can i ever find the strength to forgive him?

Okay, I know that I am a bad person because I cheated on my boyfriend. But we have gotten really close lately and I feel like I should tell him before he hears it from someone else. but how should I tell him? I don’t want to break up though because I really do love him and I made a stupid mistake. Please help me.
