Good thing that believers don't need that, because it's not available. From age 12 to age 28-30, nothing is recorded in the Bible about Jesus' life, as Nova has already pointed out.
The point is that he probably would have had time for a wife and kids before he entered fulltime public ministry at about age 30. And even after, because various women accompanied Jesus during his ministry, according to the New Testament.
There were women who traveled with Jesus and his disciples (not just the original 12, later called apostles). One description is in Luke 8:
1After this, Jesus traveled about from one town and village to another, proclaiming the good news of the kingdom of God. The Twelve were with him, 2and also some women who had been cured of evil spirits and diseases: Mary (called Magdalene) from whom seven demons had come out; 3Joanna the wife of Cuza, the manager of Herod's household; Susanna; and many others. These women were helping to support them out of their own means.
Another is in Mark 15:
Among them were Mary Magdalene, Mary the mother of James the younger and of Joses, and Salome. 41In Galilee these women had followed him and cared for his needs. Many other women who had come up with him to Jerusalem were also there.
