So, your wife knew about it for 3 years? Did she tell YOU she knew, or did she keep it to herself? Did you stop the affair because you found out she knew? Why do you think you got into the affair in the first place?
Now - to give you some advice for dealing right now: You have NO IDEA of the pain you have put your wife through. Whatever you imagine multiply it by 10 - or 100. Step one is for you to accept complete responsibility for your actions and to acknowledge that she's totally right to throw you out. Step two is to show her STARTING TODAY that you can and will be a better man in every aspect of your life; a better father, a better worker, a better friend. Tell her you know that your words are meaningless to her right now, but that you love her and intend to prove it with your ACTIONS.
You spent 3 years destroying her love for you; it may take 3 years to win it back. Are you man enough for the challenge?
