Oh, so it's a he? If it's gone on for a while, then clearly they like having you around. And you don't just invite a fuckbuddy to a beach in France, that's far too romantic - you wouldn't want them getting the wrong idea. So, with that in mind, maybe this was his way of telling you he likes you?
And I'm always proud when my friends act like dicks, reminds me why we became friends in the first place.
