They need to know they WILL face hard times, and that feelings ebb and flow. Hard times do not mean they made a bad choice or that it's a sign they should move on. They have a choice then: stay and work it out or run away and face the same situation later with someone else.
I also think they need to know how to set boundaries for themselves so they don't end up in EAs. It's so easy to slip...as it does start innocently enough. One of the affair books actually has strategies that address avoiding emotional affairs.
It's important to keep working instead of using that piece of paper as a safety net/excuse to slack off.
