Dean keeps flirting with Cas but doesn’t understand why his usual lines don’t work, so he gets frustrated and just kisses Cas, only to be pushed away and rejected.

But Dean doesn’t know the deal Cas made, so any bit of happiness Cas may feel terrifies him because The Empty may come for him. So he’d rather risk Dean thinking he doesn’t want anything more than friendship than to be taken away from him forever.
