You survive this by bringing meaning and growth to it. How can we possibly begin to forgive ourselves, or even live with ourselves, unless we've at least tried to grow and change and learn from the things we did? Experiencing shame, guilt and pity is something that is necessary short-term, because people don't change unless they have to. The trick however, is in not getting stuck in that shame and grief. Those are selfish emotions, and do no good for either the WS or the BS. If we label ourselves as unworthy people, then we will certainly live up to those standards.
So we set better standards for ourselves.
We learn from our mistakes, consciously decide that we no longer want to be the kind of person that thinks, feels and acts that way, and then we take purposeful steps to change who we are fundementally, at our cores.
Very early on in R, my wife sent me an email, in which she asked me this:
How do you want to be remembered? Do you want folks to say, poor guy, he had his demons even though he tried? Or do you want folks to say I want to emulate him because despite the horrific adversity he faced and the years it haunted him, he made us all look up to him? He is someone that I wish I could be.
I'll be honest with you. It took me about 4 years to figure how to do that. It was hard, it was frustrating, and my lack of ability to fundamentally change (I could only phone it in sometimes) only ended up doing more damage to myself and my wife. Most of the time I wanted to just give up, or just end my existence. In retrospect, I needed to feel those things. I needed to struggle and fail time and again. I needed to really get sick of being who I am. I needed to die, just not in the physical sense. I had to go back (though therapy) and figure WHAT made me think and feel and act the way I do, WHY I really did those things and what they really meant to me, and then figure out HOW to go about developing newer, healthier coping skills and thought patterns. It is no small feat, and one should not go into this thinking it will be. So you set your expectations accordingly.
And no comments about not cheating to begin with. That’s a given and not helpful advice.
I would just like to bring this up (because I no longer conflict avoid things, because that wasn't working out so well for me). I have noticed in several of your posts (not just this thread) you have made similar statements or taken similar stances. regarding telling people what you don't want to hear. From this end of the internet, it feels very aggressive and defensive, right out of the gate, and can be very off-putting to people who are looking at your post with the hope of being able to be of help or support. When you wrote this, there were no replies yet, so maybe take a moment to ask yourself why you felt you needed to add this defensive disclaimer, and what harm would have occurred had such a response occurred? What would your options be? Could you choose to just ignore and not respond at all to such replies? You could. But you didn't. For some reason, this was important to you. In fact, you wrote a longer sentence about what not to say, than the length of your original question!
This isn't me digging on you. This is me challenging you to start figuring yourself out. Writing, "And no comments about..." could not have been a happy or pleasant moment for you, and I sense instead stress and aggravation in those words, almost as if you are looking for a fight about it. So what were you feeling? What were you afraid of? Where in your body did you feel that emotion physically? What wall was going up at that time? What were you protecting?
We survive by changing. Growing. Learning. And we do that, by knowing and understanding ourselves, and by learning to love who we are, including our imperfections.
