Expenses: Division of a Child's Private Education Expenses

I am custodial parent lives in CA and dad non-custodial parent in OH. I spent about 30K on his education expenses and he doesn't want to pay 50% of share in it. Our support order doesn't say any education related expenses. It only specified extraordinary medical expenses shared equally between the parties. Can I file motion in the court to pay his share of educational expenses? He never sees child and can I ask for increase in child support amount as he is not exercising visitation rights.
