Faith,

She's been out of the house since June. Your divorce has been filed, and almost finished. She's moved on.

Yes it's unfortunate that she wasn't honest with you, but you know the cheater's mantra...

I'm sorry for you man. Don't let your anger change you. Think of the flirty girls! Think of all the good things you've done in the last couple of months. You're strong enough to pull through this. We all are.

I know how hard it would hurt me to know my wife was seeing other people, but yours has been out of the house for a couple of months. I'm not surprised at all. I wouldn't even consider it an affair, so much as getting a head start on the divorce. Now if she'd been seeing this guy before she moved out, then it might hurt more. But don't hold onto the hurt and anger.
