Help Loving mother retain custody of her children

My dear friend, Dita, is a single mother and is raising her three beautiful children on her own.  She lives in Indonesia which is a largely Muslim population.  She is a loving  Christian mother and is raising her children to love the Lord.  Her ex husband has re- married  and has converted from Christian to Muslim.  He is attempting to take her children out of the country under the guise of giving them a better education.  The only way she will have a fighting chance to keep her children with her is to enroll them in a private school.  The cost of the private school exceeds our goal but this is at least enough to enroll them and she will then be able to make the payments.  Please find it in your heart to help this family stay together.  Her children are begging her to not make them go and to fight for them.
