You pray. You pray daily and you ask the Lord to give him wisdom about this decision. And, then you submit to what your husband deems best. It's not the easiest answer, but I think that is what has to happen and that is what I did. My husband didn't want to homeschool. The Lord put in on my heart first. I took scripture to my husband and I told him I would submit to what he thought was best, but I asked him to also pray about it. A year later (we both prayed for a year), we decided to homeschool our oldest for prek. Now she is in 8th grade and it was THE BEST decision we have ever made. BUT... we made it together- united.
