So part one of this was an emotional affair that turned into a physical one (see May 15th...) So for 3 or 4 months we are trying to reconcile and work through therapy. I went to see her therapist who has a very good reputation and things seemed to go well, he's a tough guy but fair as far as I could tell. He didn't like me checking up on the cell phone bills but I did any way as I got suspicious of a new person that showed up in her life. Anyway this is crazy...
We are in therapy and they are railing on me to commit to the process and regain connection. The focal point of some of the sessions are my lack of trust which my wife is quick to provide evidence for. At our last session (8/24) she chose the topic: improving our sex life. A bit of goodness after DDay but it mostly is a step above masturbation (from what earlier in our relation ship was really really good stuff

So basically since May we've been in together or individually 2 times a week. Good stuff, everyone saying the right things. In general I feel pretty good about the therapy though I felt is was focused on me too much (guy thing?)
It turns out that shortly after DDay, maybe 3 weeks this guy shows up and my wife and him get emotional (I suspect more of course but don't have definitive proof). What is crazy about this is that she used her cell phone to talk to him. I figured out the first affair using cell phone bills, she's no dummy so I don't get it. Initially she had a reason to talk to him but the calls kept coming, durations increased. For me I saw the pattern of a call to him, a minute later a call to our babysitter, and then a call back to him. I asked her if she was having an affair and she said I lacked trust ... you can see where this is going. Finally last week our baby sitter left a cell phone bill for her to pay. Turns out she's been borrowing her phone to make even more calls.
Long story short she admitted to an inappropriate relationship (deny's physical, though that is of little consequence) with him. Our therapist who I would have described as fair but slightly biased towards her has come to my 'side', to say the least, in seeing that this therapy has been nothing but a manipulation of me and him. Initially anyway he's got it pegged as a Love/Sex addiction thing. I've read a fair bit on this today and have a clue. Reading down the list of symptoms he seems right on.
I'd really like 'street' input on this from you guys. In May I was deeply hurt, to the core really. I've recently found a great deal of strength and feel strong and confident about myself (which is a BIG change). I am so thankful for whatever clicked in me because another trip through that hell would suck. I am clearly to the point where either outcome would be fine with me, though I want the kids to have a real family life.
So now I'm viewing this as an addiction or sickness. That is good in that I'm detached and am able to put very little burden on my shoulders for her doing this. I feel a strong obligation to work through this (not necessarily reconcile, but to work through it with 100% effort), I also have a strong feeling to say F' you and I'll take the kids, unfortunately I'm the guy so that won't happen. What can I expect from this situation? What should I read? What is the process dealing with addiction/affairs? I'd love to cut my losses but I have 3 great kids (2/4/6) who dearly love their mother. I love her too, the best times of my life were spent with her.
Help.
