I don't know if this will help. But I don't answer numbers I don't recongnise. So I deleted H's no from my phone and when he used to ring - I would have no idea who it was and not answer!! I guess not everyone is as ditsy as me so might not work for all!! Also having to look up the number to dial or put into text is a faff so it just gives the brain enough time to reconsider....Good luck
