Unless, as was the case, her parents Joachim and Anna intended the marriage to be a custodial marriage.

Putting aside that your assertion is 100% extra-scriptural, what is a "custodial marriage"? After a search, New Advent did not recognize the term. What was the point in actually getting married since Joseph could have provided for her financially equally as well, if they were not married.
PLUS, the Protoevangelium says that she was from a wealthy family, but Joseph could not have been rich because they made a poor man's sacrifice after Jesus was born. This does not make sense. Given all this, if Joseph really was the old, old, uncle with one foot in the grave, as has been asserted by someone in this discussion, then it really would have been Mary taking care of him, if anything. But no one has argued that.
