Wow... Krissykriss. Thank you. I feel so much better now. I'm so glad I found this forum. I hope ten more people give an answer just like yours.
And to anyone who might post something like Krissykriss's Haiku masterpiece... Please ask yourself if you've ever made a huge mistake that you wish you could take back. Doesn't have to be in a relationship; something you said to your father before he died, a boyfriend in college that you left and just never called again which crushed him, the drunk kiss with your girlfriend's friend. Anything that you wish you could take back. Then multiply that helpless feeling times a thousand, and you might know how I feel. I'm not a dirt bag. I've never so much as looked at another woman while I was in a relationship with anyone. And up until my wife, I had never hurt anyone's feelings on any level near this.
I am moving on with my life, because A.) I have a fantastic therapist and B.) I have no other choice but to try to put myself back together. But just under the surface, I am so ashamed, guilty, and broken by what I've done. And if you feel like rubbing it in, just because you are on the internet and feel like you can say anything you want without any repercussions, then you aren't any better of a person than a guy who crushed his wife by leaving her.
