Okay, so the phsychologist is off-limits, except that she had something to do with your initial intro to the OM attorney? But then she saw how messed up he was and is helping you to get out of that situation?
As to the attorney, did you ever hire him for professional services? If not, then fine. If so, he needs to be turned into the bar.
Okay, next subject, the addiction. I get it. Most of us here probably totally understand what you mean by the addiction. I was just trying to break through using some strong language. If it was off-base, then fine. The SI motto stands...take what you need and leave the rest. As to us having our minds made up, all we have to go on is what we read here. I thought that I had deciphered your situation by reading your older thread. What we do know though is that you are feeling the addiction and it is very difficult for many people to get over the AP. Some can drop the AP in an instant. Others, well it can drag on for a very long time, years even. And that is the hardest thing of all to read how a WS is putting their BS through such pain. I know because I did it.
So, I sort of have my mind made up about you, but only because I was you. That doesn't mean that our situations are the same or the path forward will be the same.
You will have to work very hard to break this addiction. First step is NC. There is no point in talking to this guy ever again. You may want to rage. You may want to put all the facts out there. The reality is that it won't matter to him, and you will never get what you're seeking from him. Again, I know because I did it.
You need to realize that his end goal was probably just another piece of tail. Despite the feelings that you experienced, and are fighting right now, this guy likely only gave you enough of what you needed so that he could get what he needed. And to turn that one around a bit...you are actually doing the same thing. You are manipulating him and yourself to get that high that you crave so very much. You're doing it to yourself now. So you are the one in control here, not him. And it wasn't even him that made you feel this way. It was just the A itself, not the individual.
Consider changing IC's. When you find a new IC you are comfortable with, go in there with a plan. Don't use it as a weekly session to pine for the OM and wonder what would have been. Actually go in there with the plan to make yourself a better person, a person who won't cheat.
Sorry for the 2x4's earlier. I only use them when I think someone is trying to diminish what actually happened.
