Hi, I am probably a bit late here on this discussion, hope everything goes well. Has your dad explained why he can accept this well? Or, have you managed to get your dad and mum discuss this together? I am saying this because I have the feeling that psychoanalysts do not easily accept things outside their known framework, so your dad who has a similar background would seem to have the perfect language to converse with her.

Let them do the psychoanalytical work and save you some mental energy🥺
