No worries RR. I am often wondering about that fine line between validation and excuses. I know that in my H's pain and remorse and guilt it is very tempting for him to grab onto some kind of hook like that to relieve some of those feelings.
I know he has discussed some of the "mother" issues with his IC, but he has told me that she is also very direct about personal responsibility re: infidelity. He seems to actually respect this and her "straight talk" is one of the reasons he seems to feel comfortable with her. So, I am not too worried about this coming too much from his IC.
