There's a lot of emotions involved in these situations.

Not only between the couple but additionally from your readers and audiences here.

I'd propose themselves to be brave & strong - step away from the situation for a couple of days to think & reflect on moving forward. Mistakes have been made, that's in the past. But go back and discuss as adults on what's the decision in moving forward.

At the end, it's for the couple to resolve and no one else.
