First off, thanks again to everyone that replied.

Over the past 3-4 days, she and I have had some incredibly open, face to face, sit down discussions. Fortunately for me (us), we have always been open and able to talk about things - no matter what - that are on our minds.

It took me awhile, but I finally got it out to her that what she did - intentional or not - hurt like hell. To see her physically being in contact (limited contact I know, but still...) with anyone else - cut to the core and hurt like hell.

We talked about WHY things might have happened as she did - was I not paying enough attention to her, was I not making her feel sexy, did she not find me attractive anymore...and we came to a lot of conclusions, most (if not all) of them were good conclusions.

One thing we learned/realized was that our physical relationship had been slipping over the past few years, most within the past year because of the new mouth to feed in the house (now 17 month old son). We talked about simple ways to get the intimacy back into our lives, so that we both feel wanted/needed by the other person.

She said that it wasn't that I was neglecting her, or not making her feel good/sexy...she just lost all judgement.

For the most part, I've gotten past the Saturday "incident". It still pops into my head now and then, and when it does it still hurts. Probably will for awhile. I've tried NOT to make it into too much of a big deal...it's not like she was fucking him on the couch...but what happened DID hurt me.

We are back on a much better playing field now than just 2 days ago. There ARE a few positives I took from this...

#1 - my wife is very sexy and hot, and other guys think that she is too (good for her AND good for me - I'm the man!!! )
and
#2 - my wife and I still have the ability for wide open, honest communication.

I want to thank you each again for replying. Not sure why I chose to spill my life (or weekend) story here, but I did...thanks!
