Need some help with moving forward.

I have not read "not just friends" yet, but I am going to. I've looked it up on Amazon and it looks right up my alley. I'll also check out Boundaries.

I also understand that I have not been given the whole truth about everything. I'm not that naive. At this point, when she has admitted that they have kissed and then some, my mind tells me that they have had sex. Even if I can't confirm that, I don't know if it matters. They have engaged in a physical affair, even if sex didn't happen. He touched my wife and she let him. End of story.

I guess I'm wondering what I do now. She's saying all the right things. I'm in a position where I am just waiting to find out if she'll continue to do what she says. (as I was not too long ago and she failed)
I guess that's all I can do.

How many disappointments does it take to break the camel's back?

My motivation for being a good husband and being the person she wants (i.e. the things she was looking elsewhere for) is very low right now. I need to be strong, but my strength has been sapped. How do I know that my efforts won't be met with disappointment in another few months, just like it has been now?
