Either you trust your wife or you don't. If you do, this is fine. The fact that she went out of her way to tell you about it makes me think there's nothing fishy going on (she was probably worried about the appearance of impropriety). If you don't trust her, you need to address that issue pronto because if it isn't this guy, it'll be someone else (if you think she'd cheat on you at all).

If you're worried that you're not giving her something she needs in your relationship, you should start giving it to her or definitely be worried she'll look elsewhere for it.
