As a former Lutheran who converted 25 years ago I know what you are going through. At first I converted as a matter of convenience then rarely went to Mass. We raised three sons who are all adults now. The one regret I have is that due my own lack of strength of faith I did not set a good example. Over the years however I have been drawn closer and closer to the Church. I began reading everthing I could get my hands on, begining with "Catholocism for Dummies", joined a "Why Catholic?" group and read some more.
My advice to you would be to study, study, study. If you have access to EWTN, it has exceptional programming and opportunities for learning, particularly the series by Father John Corapi and the Catholic Catechism, if he can't motivate and teach you very few can.
Welcome to the Church and good luck on your journey.
