More lines in the sand

I need to think about establishing personal boundaries. Though I am critical and expect a lot of from women I am with, I do tend to be very forgiving - to the point that I will put up with almost anything if someone apologizes to me. I really am like a doormat at times. I need to learn how to balance what I think is acceptable behavior and my desire to not hold grudges. I need to learn how to distance myself from unproductive relationships - those that will be a waste of time and offer little opportunity for growth.
