Affiliate Marketing Secrets

My girlfriend is Roman-Catholic, and recently we were talking about getting married. I do not practice any religion, and do not want to affiliate with any religion. She told me that I absolutely have to get confirmed to get married to her (since she wants it to be in a Catholic church). But I do not want to be confirmed. I am not prepared nor have the interest in giving that commitment to the church. We both have strong feelings about our sides. She also told me that just because I get confirmed doesn’t mean that I have to go to church or give that commitment. So I asked what is the point of doing it in the first place? She is confirmed, but does not go to church or really practice. She also said that getting married outside of a Catholic church would “disown me from my family”. I have no problem getting married in a church…
Is it possible for us to get married, still in a Catholic church, without me being confirmed?
Any advice/help is appreciated… just please don’t preach to me, nothing is going to change mine or my girlfriends mind on our feelings of religion.
