Well, I don't have this problem because 1) my daughter is still too young and 2) my DH and I are both interested in homeschooling.
But, what I would suggest to you is that you assemble some literature that your DH could read, on the subject of homeschooling. We have a book called the Homeschooling Book of Answers and it is full of stories by different parents about how and why they homeschool. You might also want to sit down and ask your DH why he is against it, then address the specific points he's concerned about (eg. if he's worried about "lack of socialization" you could show him what some homeschooling kids do in a week).
