Maybe it would be better to say that you and GF are taking a break to give you and your wife a chance to see if you want to get back together. I don't know your wife, and there are many different ways people can react to all the complexities of life. It is possible that the fact that someone else wants you makes you much more attractive to your wife. And if that person is out of the picture, your wife might lose interest again. Of course, that could make up your mind, too. I think it would be better to phrase it as a time period when you are willing to not date GF and see where things go with your wife. However, if they don't go anywhere, you will begin dating again. And, I would recommend putting a time limit on it. For example, if there is a Retrouvaille in January, then I would suggest that you two go to that during the time period. And if she won't go, then the time might run out, and you go back to dating.
