The evidence for Jesus being married is in the Bible.
The one consistent figure in the resurrection stories is Mary Magdelene. She is depicted as being one of the women sent to annoint his body after his death. This was a task reserved to relatives of the deceased. She calls him raboni the intimate form of the title Rabbi. First century rabbis were required to be married and he is consistently referred to by this title. Jesus commands Mary not to cling to him, in Jewish custom women may only touch related men. At the Wedding at Cana, Jesus is present with his mother and best friends. The only time that was likely would be his wedding.
Besides if Jesus was sent to Earth to live as a human being and suffer as a human wouldn't part of that include learning to love as a human including all the pain and heartache associated with that? Isn't part of being human falling in love?
