Let me start everything with a simple story..
Once there's a little girl who tried to climb up a tree. Due to the difficult way up, she slipped and hang on to a branch.. The girl is so afraid to let go because she doesn't know what will happen if she will let go. She doesn't want to experience the pain when she'll hit the ground. So the girl held on to the branch even though her hands were already shaking. Her arms are hurting because of the pain of holding on. The girl decided to let go and is willing to experience whatever is there for her when she hits the ground. When the girl hit the ground she cries for so long because of the pain but she felt good after the crying.
The point of the story is the agony of holding on and the relief of letting go. Some people are trying so hard to hold on to a relationship and will do anything to try to save it. Due to the effort of doing it, they will tend to hurt each other and will even hurt himself. If all hell breaks lose and one of them will decide to let go, definitely it'll hurt but not as much as the pain experienced when holding on to something that's not worthy. You'll cry but you'll be happy eventually because you've decided to take the dip.
Feel the pain and be happy...
