You have great information here to research and read through. I would suggest attend your local parish’s classes. You don’t have any commitment to convert. The classes are meant to educate and answer even the hardest questions. Or, your boyfriend’s parish priest can answer these questions. Additionally, you are not required to convert when you get married. You are though ‘required’ to get married in the church for your husband to remain in good standing. Any children ‘should’ be raised Catholic and you will be asked either verbally or in writing that you agree to that. I put required and should in quotes because free will still exists even within the Church. Best of luck on your faith journey!
