Most Helpful Guy
Yes, that's what I've heard sometimes. It's because during vacation you have more time to spend with your partner and for taking decisions about relationship. On day-to-day you don't have time because of job, stress... and if there's something wrong with relationship you blame it on stress because of job and its rutine. So you face vacations to smooth things and strengthen relationship. If this doesn't happen, before returning to the rutine you know there's nothing to do.
Like I said, that's when on day-to-day relationship is not good and strong enough.
