This crystal moment in time is all that matters. Not all your piety not wit shall lure it back to cancel half a line, nor all your tears wash out a word of it. I can not recommend this site highly enough. After you have read this technique, and tried it in your life, go to the other pages there. You will not regret it, it can change your life.
All pain is the same.
No matter how much fault you find with another, and regardless of how much you blame him, it will not change you. The only thing blame does is to keep the focus off you when you are looking for external reasons to explain your unhappiness or frustration. You may succeed in making another feel guilty about something by blaming him, but you won't succeed in changing whatever it is about you that is making you unhappy.
