Notoday, it was me who wrote that.
What will happen IF YOU ALLOW YOURSELF TO MAINTAIN AN EMOTIONAL DISTANCE is that you will start in the next few weeks to see patterns in his behaviour around lying/secrecy which you didnt see before.
My relationship took a poor turn after we moved back to my home town two years ago, as he blamed me for the move, and he was unspeakable about it, even the kids were dragged in by him, which prevented them from settling. It never occurred to him that my unhappiness was because he had already been doing this with young girls for 3.5 years by then, with the attendant withdrawal, aloofless, coming to bed at 3am if at all, emotional neglect of me etc etc which goes along with infidelity. But I didnt see it either, I even went to therapy alone to try to work out 'my issues' in life.
It was only after we moved here that I finally became exasperated, and then I started to notice GENERAL patterns of lying and defensiveness, but still didnt suspect, except subconsiously.
I was able to force a confession the last time, because I had effectively, I suppose, been studying him in a new way previously. And he was able to admit it, because he had no choice. I had moved out of the bedroom, seen a solicitor, and then we went to Relate, where I wouldnt back down despite his denials. His sense of shame was so overpowering, he COULDNT admit it.
It does help to look at it from his viewpoint, and his personality, not to sympathise, but to jolt yourself awake enough to see the obvious in him.
Whilst you are powerfully wanting to believe that he couldnt lie this way etc etc, or do that to the kids, it gets in the way. It is , literally, denial.
Also the lady upthread is right, he senses your ambivalence, and that combined with his desperation is making him refuse to admit. He hasnt accepted he is busted, because you havnt.
