I have this sort of ritual with a friend of mine that we do every night. I tell him I’m going to bed because I always sleep before he does, and he whines for 5 minutes XD. Then he finally accepts it and I tell him I love him, for him to take care (if he’s not feeling well or if something’s going on I tell him “Take care of yourself, ok?” because he never puts his own health first) and sweet dreams because he’s prone to nightmares. He responds that he loves me too, for me to stay safe (because I always wake up earlier than be does, and he worries), and for me to sleep well (because I wake up a lot in my sleep). Then he sends a few <333s, i send a few <3s (after a few <#s) then he says g’night, and i respond with the same, then i go to bed.
I know it’s really simple and cheesy but i love it.
