Thanks for the perspective Hope. Yes, you're right, we both know that if it ever happens again that I will be finished for good. In fact we almost hit that point a few months ago when I found flirtatious emails with another female coworker. He realized it was inappropriate and deleted the messages so I wouldn't find them and freak out. Well, they weren't really deleted and I did find them and the fact that he tried to hide it made the situation ten times worse. At that point I was ready to walk because I told him I will not go through this again. So he knows I'm dead serious and I need to just remember that and not spend energy worrying about it.
Again, thanks, this is just what I needed today.
If you love somebody, set them free. http://tinyurl.com/2empx2g
