When it is time, give plenty of notice to help transfer knowledge to the new person in your position and or find a replacement. Tell him that you have been offered a chance to grow, and prosper in another job. It is a chance to better your self and the life of your family.
If he takes that personally he is not really your friend.
Long gone are he days of starting as a clerk and working your way up to CEO. That simply does not happen any longer, I'm sorry to say. Be professional. Be honorable. Keep focused on your priorities. If it gets ugly, take the high road. And keep us posted. Good luck.
