Hi Not Alone,
I doubt whether a) there will ever be an end to his questions and
b) he'll ever be satisfied with your answers and agree to a fair resolution.
So... I'm wondering whether you really need to respond to any more of his inquiries... even by email?
Just from my experience, it simply is never enough, and absolutely never right, where N is concerned.
I am so sorry he is having this effect on you. You know he's just toying with your fears, playing on them... and yet it's so very difficult for a caring, conscientious person to not respond with explanations.... I do understand. But if it's not business anymore, and you're not friends anymore, then... what's the point of continuing any sort of correspondence?
Would you feel safer to block his calls and emails? Just wondering.
With love,
Hope
