Why be Catholic when I’ve been baptized?

A reader writes:I have a friend who is an Evangelical. Over the years she has gone from verbally attacking the Church, to being more silent on the subject, to being somewhat accepting of our existence. Now, she asks me the question—“If I believe in Jesus and who he says he is, and I have already been baptized in the name of the father, son and holy spirit, why should I convert to Catholicism? I have an answer but am not sure it is the correct one. What would you say if you found yourself in similar circumstances?If I have a picture of the woman I love and several of her letters, why should I marry her and live happily ever after?The faith is the fullness of what Jesus wants to give us. Why settle for less?
