Casteism Question

WJKK WJKF, i am writing this in this sub due to me being completely lost and almost at a spot in time where im going through almost an identity crisis. I have just turned 18 and i am currently in a relationship with a jatt sikh girl. Recently i have found myself drifting from sikhi as well as questioning gods existence as well as human overall. I have two questions and need direction. I am from a ramdasia julaha caste i dont know what that is and not sure if it is low. My main problem is figuring out if her parents will approve of me. As well as how i can come back and get closer to god. Will her parents not accept me? Career wise i feel as if i am doing pretty well for myself, Me and my brother who is 5 years older than me worked together 2 years ago to start our own marketing agency. I am consistently doing great numbers in my business so the occupation side of the situation does not matter. My parents are also very well off and have built a great life for me and my siblings. Will her parents not accept me just because of my caste? How can I approach this situation.
