I'm happy to see that he does have real credentials. I personally am turned off by his rhetoric. Infidelity is bad enough, there is no need to exaggerate for effect.
See, I don't think he's exaggerating. I think he's merely reporting on his thousands of consultations with women who've been affected by adultery. I'll take him at face value, since he's had far more experience than I've had just studying a few hundred on a message board and my own sitch, but AS for my own sitch -- and re-reading my journal recently where I recorded all of my thoughts and feelings at that time -- I don't disagree with him. I choose not to dwell on it here, as it would do no one any good, but the sheer depth and intensity of the wound is unfathomable.
I do agree with one of your main points of your original post in this thread, however. I do think we should give more weight to those giving advice who have SUCCESSFULLY dealt with infidelity, ended their spouses' affairs, and who are successfully healing their marriages.
