I'm feeling post affair guilt and anger
Why do you feel anger and guilt?
I felt guilty because I've hurt someone badly by falling in love with another person.
You're supposed to be faithful to your partner. Have you confessed and apologized?
Not yet but I think I should. I want to move on but not seem like a total bad person either.
You have the right thinking there. Tell them the reason why you want to break up first though. That way they won't be held wondering if it was anything they did wrong.
