The seven year icth is a point that a lot of couple go through. It is the point when you have been together so long that you are tired/bored with your partner, but you have not been together long enough to have accepted the rythem that is being in a relationship. Some people miss being single and would like a different partner. Other people just miss the freedom of being single and having no strings attached but they do not want another partner. It is a "rough" patch in a relationship.
They are starting to feel the strain of the "Seven year itch." They will get throught it if they try hard, enough.
