See the problem is, you're talking to a pretty well, world-wise, experienced, cycnical (use the adjective of your choice) group of guys.
So, with much respect to you & your wife, because I/we have NO IDEA of what your personal situation really is, nobody here would take that kind of nonsense talk ... well, OK, 90% of the guys here wouldn't take it.
We'd tell her to get a move on, why wait?

But that's because we have WAY too much of the wrong kind of experience, and we're just a tincy wincy little bit on the jaded side (yep, especially Momo, who's all of, like 26).
But, that may not necessarily be the situation with you, so if you have a decent relationship going, NOW would be a good time to start the sessions with the
relationship psychologist, not when there's trouble brewing at home.
Good luck ... whatever you decide to do, you're going to need it.
