Thank you tripod, you are a wise man indeed. I do think you've hit the nail on the head in several respects.
It's funny (well not literally), I'm actually not angry - just deeply saddened. Obviously something that comes from my very strong feelings toward her. I would love to help...I try to support her in every way I can, including reinforcing how attractive and *wonderful* she is, but I guess she needs that assessment to come from someone who is clearly not as biased as I.
I really have no problem with online fantasy fulfillment - it's the real "meat in the hole" that wrenches my heart from its valves. I do not know whether she has met anyone. The last time this happened, she swore she hadn't. I'm not so sure and, even if she hasn't, the question remains "what if". The only thing none of us can always resist is temptation. Eventually, a liaison is bound to ensue and, no matter how much she might regret the morning after, the deed will nevertheless be done.
I've dealt deep inside with the obvious trust issues that arose last time. Hard though it was, I kept my potential fears of "where is she, what's she doing" when working late, etc. to myself. After all, a cage only makes the desire for escape that much stronger. It's always in the back of my mind though...the reason I Googled her alias today, just to give myself some reassurance that things were still okay. Evidently they weren't as I found this site, her paid membership and her private parts plastered all over the place in glorious Technicolor.
I don't know how easily I can trust again this time. Truthfully, I was (and largely still am) prepared to go the distance to keep my family (which means everything to me) together. That said, if my wife needs to continue in this vain in order to feel okay about herself, it will destroy our family, no question, if it hasn't already.
There comes a point when caring, empathy and compassion are all used up and, I confess, I am very close to that point now. We shall see.
Thanks again for your very kind and supportive words.
