I agree with what Mach posted about why to kill the demons that keep us from trusting.
It is something I still struggle with from time to time. It will bite you in the butt time and again, in a future R with your spouse, or with someone else, if you don't...
You have to really be willing to be honest with yourself about things though or you will never get to that healthy place.
My story, is no better or worse than yours or anyone else's (although you may be sitting there going "Thank God I am not her", I might be if I was reading it...)
My point, is simply that anything can be worked through and overcome within yourself, with the right perspective.
Justification, simply, doesn't work for me anymore. Killing those demons, does.
