Letting my wife talk to other men.??

In my first post i talked about how i wanna share my wife with another man and how horny it makes me just thinking about her being a slut. Well recently i've let her start talking to her xbf from high school on facebook.
The sex has been great just thinking about them talking to each other. My question is will is regret this or should it and let take its course.?
Just wanted some opinions that's all.
