Mama, he knows he's in trouble with you with your marraige and truth is his insecurity is emerging from his guilt. He knows he's the one in the wrong so it not only is making him insecure and pry, it's also making him project the problem onto you as your fault so as to deflect his guilt.

Don't give in. he's wrong and he knows it. He goes to T himself and knows it's confidential and I'm sure he has his private areas that he doesn't share. He needs to give you the same respect not to ask you for it
