You Should Never.

Although you may never be happy all the time, you should strive to be. If there is ever anything that causes you pain, that causes you to be unhappy, you should change it. You should learn to let things go; the ones that hurt you, tear you apart and prevent you from smiling. Sometimes, the things that make us happy momentarily aren't worth holding onto. When the minutes of dissatisfaction are more frequent than the glimpses of happiness, you should learn to let go. No matter how much it may hurt to do this, sometimes it's necessary in order to properly heal, in order to move on to something better. Never stay because you are afraid to leave. Stay because you want to stay. Stay because you want to grow together instead of growing apart. If you feel like things are falling apart, if you feel like the pieces don't fit together, don't force it. This isn't to say that it won't take a bit of work, it will. This is just to say, two people should never have to force something to work. There shouldn't be an upward battle; all the time.
