y you shoulod never even sleep with someone from outside your beliefs

my brother in law and his daughters' mom are fighting over if their daughter should attend our church school or public school. They have been fighting about this all summer and frankly its getting on everyone in the house's' nerves. his wife was hiding in my room with me last night while they were arguing over the phone. its not her decision really hes got full custody of their daughter and shes better off at the private church school getting a better education but she thinks she be better at the public schools she attended.
