Breaking up a relationship is hard - particularly if it's not your preference. Heartache can be experienced even when an unrewarding relationship terminates, because, at the very slightest side, you have lost the touching venture you made in that relationship. There may be a sense of breakdown, desperation, loss, misery, fear, or extreme anxiety. In several cases, the length of the relationship amalgamates the pain of loss - a divorce after half a life span together can appear like the end of the world. Partially it is based on how much you had vested, morally, emotionally and monetarily. But even temporary relationships can absorb an investment in desires and in expectations for the future, and their loss can be likewise heart-wrenching. 

The loss of a spouse through death is an evident source of heartache, but relationships breakup for several other reasons. Couples are spaced out generally because they:

Don't care about or desire the same things - conflicting values and interests

Don't know how to maintain a mutually rewarding relationship - not astounding if you haven't experienced constructive role models

Have problems that the other can't put up with - neurotic or insulting behavior or illnesses that sternly limit the relationship.

It's essential to keep an eye on the reasons for why a relationship breakup occurs.
