It seems that the common answer is that you are afraid of the commitment, but if you were to look at it logically, by walking away or distancing, you may lose the opportunity to have the relationship, anyway. I've been celibate since a seven-year relationship broke up five or six years ago. It's human nature and conditioned response. Look at what Clinton is doing now in Kosovo and tell me what we are doing is right. If we don't get what we want, we lash out with the primal instincts.
Violence is the weak-minded person's way of acting out.
Within the Christian faith there is a lot of disagreement on many issues. The ministry and life of Jesus seems to contradict many of the modern church's teachings. Jesus did preach love and forgiveness. The New Testament is full of commandments to love your enemies and those who persecute you. We are never told to hate or become violent.
