It is time to divorce when all avenues have been exhausted, including professional counseling to bring a fresh perspective. Sometimes the love is just gone, but if it is still there then there is always hope. When there is no longer a willingness to accept and compromise, no longer a care for your partner's happiness as well as your own, beliefs and goals no longer coincide, there is no longer trust and respect, then it is time to move on. The commitment is gone, and nobody deserves to be miserable in their life.
