I gave this some thought and like most everyone else, I believe in total honesty, that said, I have a Buddhist's perspective on guilt that I would like to share. When we mess up and we "feel like shit" we are like a thirsty animal wandering around looking for fresh water. We are seeking a solution to our new "problem" constantly. We just want the pain to go away and we will stop at nothing until it does.
Well, the pain you feel is YOUR pain it is also the potential pain of your partner that you are taking on. We think that there must be a solution to this, some sort of a cessation to the current wretched state that we have caused for ourself. We then turn to the one who loves us... THE SAME ONE THAT WE HAVE POTENTIALLY HURT! We think that some foregiveness or even ABSOLUTION would take away the pain... Like when we were young and had a financial problem and couldn't handle it, and ask for Mom and Dad to find the solution.
We think that we would feel better if we got it off of our chest.
That is an ILLUSION
All you are doing is walking up to the one you love and punching them in the face. They might forgive you... but you will have RUINED their world. Do you have the right to ruin your loved one's world? Damn straight you don't, especially because of your careless behavior. Your careless behavior is going to saddle you with guilt... THAT IS YOUR GUILT, DON'T SLOUGH IT OFF ON YOUR LOVED ONE, OR TRY TO DRAG THEM INTO YOUR LITTLE WORLD FULL OF DECEIT AND SHAME! THEY DON'T DESERVE THAT KIND OF TREATMENT!!!!!
I am reminded of the old movie scene where one lover is holding the other in their arms but they are dying at that very moment. The dying lover is frantic to try and tell the other some bit of infidelity that perpetrated earlier in their life. What does the surviving lover do? They tell them to hush, that they don't want to hear another word. They usually even put their hand gently over the dying person's mouth, so as to not hear it, even if the dying person didn't want to listen.
Our reality is subjective and not always very accurate, but that is okay. We are all building a Dramatic movie that will play back at the end of our life right before our eyes as we die. Try not to add this crappy chapter to it okay? It's bad enough that it will be in your movie as you capitulate your life, why insert it into your loved one's? Wouldn't you rather have that chapter left out of her life? How much do you love her? Enough to keep your damn mouth shut for eternity? Do You REALLY LOVE HER?
Of course, if there is a chance that she could find out, things are different. Some people appreciate honesty, and others appreciate piece of mind. But you don't really have the right to ruin your partners reality for your own absolution. You need to foregive YOURSELF, not seek foregivance in the arms of your partner. But, it is your call obviously, I just wanted to illustrate the nature of guilt and foregiveness, and point out that they are not always what they seem. GOOD LUCK!!!!!!
