Well the money he spends you could go out for a meal every night lol… tell him just give you the money and put 5 random places in a hat or something, theme park, skiiing, god knows.. something u have always wanted to do. And pick one out a week or month, and do it. So he has something to look foward to. But its easier said than done.
Ive come off face book as well. You get hastled on there aswell for it. To be honest i dont get out with my mates anymore. And i still manage to get it . Why dont he try hypnosis. Mine was £85.. but i dont know how much it will be near you. No harm in trying tho.
