The return that some posters are talking about is once your H realizes that you have 'moved' on, whether is to a new man or just 'moved' on without him, he is going to want you back.
He will more than likely beg, plead, tell you he will dump the OW, tell you he will do anything to save M, tell you he will change if you will give him another chance.
This usually happens when the one who thinks they have the cake and can eat it too suddenly sees that the cake has left for a different party.
I think everyone is wanting you to be aware of the possible (more than likely) return that the H will do. And want you to think about it before it happens.
Thinking of you.
