With all due respect, I wouldn’t forgive cheating. You’ll always be wondering if they’re doing it again and it will eat away at you - I bet this is something many people who “forgave” their cheating spouse are actually feeling but have learned to hide it well from others. Maybe not every single betrayed spouse, but I’d be willing to bet a lot of money on the vast majority of these marriages never being as happy as they were before.
I’m so sorry this has happened to you, though. I’ve never been married but I was cheated on once, it hurt like hell (and he tried to blame me for thinking we were a couple - he was the one to ask me out and do much of the “chasing”! It’s amazing what some people will do to stoke their own egos).
I think this blog would be another helpful resource for you: ChumpLady.com - Leave a cheater, gain a life
Good luck in your journey!
