I would think wishing him a fun weekend and a nice time, will play on his mind. The person who wants him wishing him a great time will not be what he expects.
I've said it by text to my h, a friend said " that's mean you probly ruined his whole weekend, he will/ should be wondering why you said it and what you meant! " the funny part is now I mean it, if he really wants to leave me and I have to suffer all the crap he better be having a great time.
