A question for Catholics. Is this strange?

Is it strange that I really believe in the power of the rosary and absolutely adore the blessed mother, but I'm not Catholic. I actually grew up Baptist and now just consider myself a spiritualist (and don't ociate with any denomination). There have been times when I wanted to convert to Catholicism, but I don't agree with all of its doctrines, so I really don't know what to do? Should I just remain as I am and continue saying the rosary, or do you think I should make an effort to complete the RCIA cles?
