This is an interesting subject. In today's mores, this relationship when he was 15 and she was a 40 year old teacher in the same school he attended ( a Jesuit school) in a class where Bridget's daughter was a classmate of his, this relationship would be considered pedophilia and punishable by imprisonment for Bridget. So one wonders if Bridget is a controlling NPA+ type victimizing a young N or NA-/=.
But looking at the information on the web, the guess is that Macron is an NPA- and she an NA=. So she really did then and now put him first and look after him to protect him.
