Not true. Consider the family of the Duke of Norfolk... Catholics.
Andrew Parker Bowles dated Princess Anne (and according to some sources they had a passionate love affair)... Catholic.
Of course, he's going to know Catholic girls from "good" families, but William also knows the rules. He might date some, might even fall in love with one, but won't marry one.
