Why Couldn’t your other son deliver them ?
If your son has mental health and drug problems then he will not be thinking in any way like we all are he will possibly be seeing things in a vastly different way He may even be thinking it’s all a trap to get him to the house or he may be thinking he has made a mistake and can’t bear to be seen as making a mistake
If you haven’t another family member who could help please do not give the parcels away or destroy them or send them back that would be another nail for him just put them in a spare room under a bed or in a cupboard and forget about them
If I was you and you ever have to contact him in future I would send the same text to both husband and wife so they both know the same information at the same time
If he is mentally ill, on drugs and she’s mentally abused by him is the grand child safe ??
