After that's done, go out with your friends and take a sexy group picture. Post it with a caption about how you're all single ladies having fun. That way, when he sees it, it'll be clear that you're unattached. Plus, it never hurts for him to see a gorgeous picture of you.

Instead of being blunt, say something like, "Your shirt is cute. Did your girlfriend pick it out for you?" Hopefully, he'll tell you that he's single, and then you can tell him that you are, too.
