If a friend put me in that position
I would have trouble calling them my friend. I know that people who feel attracted to a person, their rational sense goes out the window -- so they might have to be reminded -- because putting you in such a position ("don't tell my spouse") makes it impossible for you to keep an emotionally healthy mind.
That type of necessary "pretending" as in not letting on that you are withholding information that is very pertinent to their life, is not behavior that is a good idea to practice.
