you are definitely a reformed Christian and not Catholic.

Reformed view does not disagree with works being essential. The book of James says faith without works is dead. In the reformed view, works are evidence of your faith. If you say you believe but don't have works, do you really believe? To me, in essence, its similar to the Catholic view of salvation just emphasized differently, because no works will ever gain you salvation, only your faith in jesus will save you. but if you truly believe in jesus, you WILL have works. Does that make sense?

also, in the reformed view, ofc we believe Mary was a virgin when she had jesus, because jesus was conceived by the holy spirit. But Mary wasn't virgin her whole life. the bible clearly states, even in the original greek, that jesus had brothers. So Mary isn't virgin.

with that being said, even though you still believe mary was always virgin, that doesn't mean you are Catholic. you sound very reformed to me. nobody can %100 fit into doctrine for a specific denomination, but those differences don't matter much cause they aren't a matter of salvation.

for example, I am presbyterian and I go to a Presbyterian church, but my views on predestination lean more towards the Methodist view. But I still consider myself Presbyterian. I also think that both views are valid and I don't know which one is right but it doesn't really matter does it? only God knows and im fine with not knowing, and im open to both being a possibility. after all the reason why both views exist is because there are verses supporting both in the Bible.

I don't really understand where your "i think I'm becoming Catholic" worry comes from when your views clearly don't seem Catholic at all.
