Hello Karen (not your real name, I assume that don’t worry),
Working with couples or someone in a relationship is obviously a bit different from the Good Girl’s Challenge as that is aimed at those just starting out. There’s lots of very effective options though, however as with anything as soon as it involves more people it becomes much more complex to get right.
But I’m sure I can come up with something! I’ll have a think on it this week.
