Once you have selected the third person, in this case a male, allow your wife to exchange emails with him, maybe even ask some questions about previous encounters etc, then both talk with him on the phone, leaving her to complete the call, after all she will make the final decision. That's the easy part, the next part is the actual meeting, his conduct when in public, bringing up the reason why you are all there and not just talking about the weather. Allow your wife and him to chat a bit by themselves whilst you order a drink at the bar, then later take your time and enjoy what will happen. Your wife will make the first move, be it to or with you or him. Let her be the master of ceremonies.
