Hello dadof3plus1: Thank you for bringing your concern here to PC. I see this is your first post. So... welcome to Psych Central.

I see you've already received some detailed replies from other members. I doubt there is anything of value I could add to that. However here are links to 7 articles, from Psych Central's archives, on the subject of emotional affairs. Some of these may be more applicable to your wife than they are to you. However, hopefully, they may still provide you with some insight into the situation & how to proceed:
