How long is too long in a relationship?

Sometimes we stay in unhealthy relationships for too long. For many reasons:

  • I have invested so much time and energy into this, it can’t fail.
  • Will I ever meet anyone better?
  • Holding on to the idea that they will change.
  • What will my friends and family think?
  • Who will I be without them?
  • I will have to start dating again and I really don’t want to.
  • What will I do in the evenings?
  • Who will I go out with?

What was it that kept you in a relationship for too long?
