If you need more help, email me. The Catholic Church today is strongly committed to the idea that marriage preparation programs can help couples avoid the mistakes that have destroyed too many marriages.
Most parishes require some form of marriage preparation.
However, they usually are open to input from couples in selecting a process which you think will best suit you and your partner. It is important to speak with someone who is qualified to help you deal with this before you make wedding plans. If you email me about your situation, I can sort it out for you. The only way to know for sure is to talk with someone who is well versed in Canon Law. There are so many variables that each situation must be examined individually.
