ssmguy...I had commented much earlier on this thread, how as part of the justifications that cheaters make, they tend to think that somehow they are different than other cheaters. That somehow, "my reasons for cheating are better, or the way I go about it is better, and somehow that makes my decision to cheat different than the other cheaters out there".
Your post about telling upfront that you are married is part of what I was saying. Your telling you are married upfront doesn't make you better than other cheaters. It doesn't make you different. Other cheaters who may not say they are married are not "worse" cheaters than you are. You are again still trying to find a way to justify it all to yourself and make yourself different than they are, but you are not.
I hope you can maybe go back and review this whole thread and read again all the responses. I also hope that somehow, any of this thread will help you make the right choice and DO SOMETHING to change your current state of affairs.
