Relationships I believe are not meant to be short but long lasting and even forever.
It actually breaks my heart when I hear relationships break-up. It's sore. Relationship is divine and it's sweet,
When you have any misunderstanding, the next thing is not to break up. The next thing should be how to repair it. I know it's hard but not impossible, though.

It all depends on one's level of tolerance, understanding and maturity
