Give him a bit more time, then call him if you haven't heard for him after a few more days. Keep the conversation casual, you might want to talk about something you discussed on a date. Keep in mind though that he might not be interested, so watch out for any "hesitation"
Don't cry, don't regret and don't blame
Weak find the whip, willing find freedom
Towards the sun, carry your name
In warm hands you are given
Ask the wind for the way
Uncertainty's gone, your path will unravel
Accept all as it is and do not blame
God or the Devil
