What do I do?

My dad said if I convert to catholicism he wont consider me his son anymore and said he might stop talking to me altogether. he said it would be like me betraying our family for not accepting his reformed presbyterian theology. my mom said the same thing asking me why im disrespecting my dad and don't trust him and said im being rebellious. what should I do in this situation? he also told me to stop studying catholicism and just accept calvinism and not question it, just "believe". my parents basically said they could never accept me becoming a catholic....
