Saving my marriage by focusing on ME!

[Oxford1]

I was told by an outside source that when WW says to me " how are You" or texts it to me ( which she tends to do every few days) that I should reply with;

" My wife has a boyfriend"
In a calm relaxed kind of flat affect type of tone.

Opinions?

I have my own but I am curious what the more experienced DBers and even Newcomers think...

I would love to know what former WW's think of that comment.

Thanks
Ox
