uof,
I wish I could tell you how to stop him from going or seeing the ow, short of you going with him, But I can't.
What I can tell you is that you aren't alone. I just realized that my WF has pulled a fast one and very well may be out with OW which is also a WS.
When I realized it I ran a gamet of emotions that crossed between a resemblence of the exorcist and Sybil <img border="0" title="" alt="[Mad]" src="images/icons/mad.gif" /> . I felt like I couldn't control myself. THen it came to me. Why go through this whhen you know he isn't going through this and if I continue to go in this route I will lose my focus and my mission. So that has calmed me. I was so angry I wanted to break things. So ok I'm back now.
Anyway, something that came to mind is in Dr Harley's basic concepts about "Instincts and Habits" I recommend you read it too (link below). If I am not wrong this is how I took it. It says that instincts are patterns of behavior. Habits are learned through practice.
Well instincts are kind of things that we act on and are triggered. My trigger: I suspect my WF is out with her. My instinct: anger. Past habit:
To act on it, have an angry outburst, demand, Lb, etc.
If I do these things based on instinct I will not achieve my goal. So I have chosen instead of LBing to calmly realize he may be or he may not be but I will not allow it to ruin my night. So I will do other things, etc. I don't know if this helps or not but it calmed me down.
So what is your mission? What are you trying to achieve that Lb will interrupt?
Sorry that we are both going through this but I believe we can prevail. I wish you the best. Love, peace and joy to you.
