Unhappy alone or unhappy in a relationship?

A relationship break-up can really sour future relationships. Sometimes, one may tend to wonder if it is a wrong decision to end a relationship despite their dissatisfactions with them or when exactly is the right time to end an unhappy relationship?

Should one just hang on to an unhappy relationship hoping for a change, and or, should there be a time when one gives up on an unhappy relationship? A psychology lecturer at Francistown Institute of Health Sciences (IHS) Anita Lebengo says that it is never healthy to undertake anything that is unpleasant to one's well-being.
