He must've forgot. You just made it official that you two are bf/gf. Cut him some slack. Just because he isn't the type to do something like that, doesn't mean he can't screw up once in a while. I mean, he is human, right? Besides, if you call him up so soon and start blasting him out over a phone call, then that makes you sound needy. I'd hate to see you down the road if he did something so cruel as to *gasp* ask for personal space... Hate to sound heartless, but, let it go.
