Depends on what's going on in the relationship.

My best mate got really down about 2 years ago due to his girlfriend wanting a "break", but she really just needed one to clear her head and get on with her studying. She had every intention of getting back with him after all the exams and such were over. However, she didn't tell him, so by the time the exams were over, he was too far gone to be with her again.

That boy has nothing but bad luck with relationships.
