I too did the on again, off again homeschool route, so when I brought up that I thought we were really called back to homeschooling, my dh was a little worried and skeptical. But, our children were in a private school, which was expensive, and because his company hasn't done as well financially this year as last, it was actually helpful for him to be more positive about h-schooling, in order to save money on school tuition! It's expensive!! I am fortunate that my husband doesn't even consider our children going to Public school, so I don't have to worry about that.
My husband is very laid back about the homeschool, more than I am really, so in a way it is good, in a way it's not, because he just goes with whatever I am doing! And thinks it is great! Oh, they missed a day of math? No big deal! Just do it tomorrow. We didn't get our reading done today? That's okay! I am sure you did a lot! It'll be fine!
It is good, don't get me wrong, but sometimes, I think I need a little more accountability for myself! It is true, if we had no fear at all, or had our perfect way of homeschool life, it would come much nearer to unschooling than anything else

, but because we just can't seem to take that route, the Charlotte Mason, relaxed is the best way to go for us! My husband doesn't really understand it, but he sees that my children love to read, and he thinks that is great, because he never had that as a child.
Well, I would say, just encourage your children to make things/art projects, etc, for your husband when he comes home and for them to tell him about their day. Treat him as the Principal, call on him for discipline issues when necessary, involve him as much or as little as he desires. A great book I got for my husband from the library is, "The Homeschooling Father" by Chris Klicka. Really short, concise and good for the dads to read. And pray, pray, pray! I can't complain any more to my hubby about it...we've gotta stick with it this time! He said he is done with the flip-flopping around!
