I am a Muslim guy dating a Hindu girl

I am dating this girl for almost a year and we tend to agree on everything. We don't believe in religion but still kinda scared that what if our parents come to know about this her parents live Europe so that won't be a problem but if things get serious I don't want to convert her and shit bcz even I don't believe in my religion. I am really confused about what to do bcz we really like each other and I don't want things to end due to religion in which we both don't believe in. Pls reply to this we really like each other and are confused at this point. Also my parents are strict about the religion thing but I think they will understand eventually
