I totally agree and the person that gets the multiple chances - never even recognizes that they are getting them. They just do not get it, which is why the 'chances' are wasted. 'Chances' are just another step in the never ending dance.
I can still get a little heartache when I think about it to much but my head takes over. Chances are for suckers, lol. My giving of chances was just a nicer way for me to label my complete and utter lack of boundaries. I liked to think of myself as compassionate and caring and the reality was that I was a cowardly doormat that talked a good game but did as much about changing the status quo as the other person - which was zilch. Wait around and give someone else the chance to change and never do so myself. Bleck.
