If just dancing together, and there are other people to supervise okay, after the dance, or kissing, easy to go wrong. Take a step back, even if your wife really doesn't have anything else in mind for her dance partner, you're a man, and there's a woman who dances with you who walks with you on her arm after the dance.
That said, a man still has to be generous. When you see this situation, you are angry as you should be, you have been angry and your wife has explained. Then this thing can be put down for the time being. The next step is to see how your wife behaves, if she really cares about you, she will properly distance herself from her dance partner, otherwise, you know.
As a man with a potential love interest, I would definitely call up my brothers to go talk to him. Get everything straightened out as far as the law allows and then it's all settled. It's time to get on with your life and get divorced.
