My Wife cheated, I am devastated.

Nope no idea what year it is.
Did you know humans share 50% of their DNA with bananas?

Please, tell me what is that therapist will say.
And listen, cheating does not destroy sacred.
Get over yourself. Its no biggie.

Nup, cheating is cool, hip, fun, who gives a **** about the other person and their feelings, let alone possible deceases you may pass on, should you sleep with both, especially if the one you cheat with hooks up with porn sites/dating sites and has his smorgassboard.

She's letting it all out.
You're willing to try.
She may have held in anger for some reason, perhaps you spent hours upon hours with your "baby" that being the business, instead of your "baby" that being your wife.

See how things go, I'm not advocating what she did but the fact that she's told you and still talking about things, wants to seek counselling suggests that she still loves "you"....

If someone isn't around for a long time a relationship can turn to friendship, sounds as if you both still have love for each other and that's worth working on in my opinion.

It will be a tough battle you will have with yourself in trying to live through that. Its one that you can win. Seems you are on track by forgiving your wife. Next step could be to focus on self rather than the other man. Someone once said "Resentment and hatred are like poison you are taking yourself in the hope that it will harm the other person". Its hard not to focus on another man who may have ruined your relationship. Focus on your self, your dreams, health and personal achievements more. This will help.
