Advice for wording LC e-mail

[Poing]

I have had an e-mail from someone I am low contact with. This person, who I was previously close to, knows the reasons behind my low contact. They have, however, minimised their behaviour and have displayed some traits of narcissism/personality disorder, which has made reconciliation unlikely.

They have recently sent me an e-mail asking if I am cutting them off and how they love me and how hurt they feel. Does anyone have any helpful phrases I can use to not bring up their behaviour again and instead grey-rock them? I have tried Google unsuccessfully

Why bother? Delete and don’t reply.

I wouldn't reply when someone I went no contact with started sending my daily texts that I wouldn't answer, I just blocked them. Life is too short to worry about them, and by responding you are opening up the lines of communication by ignoring you keep them at a distance.

Dont reply. It's what they want - to suck you back in.

Never reply

Do not reply! They are just trying to get a reaction from you.

I've read before on here that a good technique is saying, "As you know" then going on to say what your boundaries are and (briefly) the reasons they're firmly in place.

Sorry, just realised that isn't quite what you asked. Could you say, "I'm sorry you feel hurt. As you know, I am also hurt. Because of that, it's best we keep our distance."?
