Joseph's reaction

Over a thousand years before the birth of Christ, David wrote this Psalm.  The Psalms are considered hymns, songs of worship and prayers of desperation  to God- this one seems to fit what Joseph and Mary had to deal with.  It would be amazing to be visited by an angel. 
Ps 19:7
7 The law of the Lord is perfect, converting the soul;
The testimony of the Lord is sure, making wise the simple;
NKJV

Matt 1:18-25
18 After His mother Mary was betrothed to Joseph, before they came together, she was found with child of the Holy Spirit. 19 Then Joseph her husband, being a just man, and not wanting to make her a public example, was minded to put her away secretly.

Joseph seemed to have the same reaction to this as Mary, "What!!?  Wait a minute..."   Joseph, like a lot of men, came up with a plan in his mind and knew how he was going to fix things.  I don't know how much of this he actually told Mary.  If she knew, it would have been an incredibly difficult time for her.  She trusted God, believed Gabriel, and now she would've felt incredibly alone. 

This is how God worked it out: 
20 But while he thought about these things, behold, an angel of the Lord appeared to him in a dream, saying, "Joseph, son of David, do not be afraid to take to you Mary your wife, for that which is conceived in her is of the Holy Spirit. 21 And she will bring forth a Son, and you shall call His name Jesus, for He will save His people from their sins."
22 So all this was done that it might be fulfilled which was spoken by the Lord through the prophet, saying: 23 "Behold, the virgin shall be with child, and bear a Son, and they shall call His name Immanuel," which is translated, "God with us."  (Isaiah 7:14)
24 Then Joseph, being aroused from sleep, did as the angel of the Lord commanded him and took to him his wife, 25 and did not know her till she had brought forth her firstborn Son. And he called His name Jesus.
NKJV

Joseph strikes me as a simple man, a carpenter.  He's honorable and keeps his word.  Obviously he has great strength and faith that God would choose him to take care of Mary and Jesus.  It's important to realize that during this time period women were stoned to death for adultery.  Joseph and Mary were asked to believe and do the unacceptable, the impossible.  But the purpose behind what God had in mind is beyond comprehension. Both Mary and Joseph were from the lineage of David fulfilling this prophecy about Jesus:
Isa 9:7
7 Of the increase of His government and peace
There will be no end,
Upon the throne of David and over His kingdom,
To order it and establish it with judgment and justice
From that time forward, even forever.
The zeal of the Lord of hosts will perform this.
NKJV
