Life love and life

I am a girl in mid twenties. Two years ago i fell in love and that he gave me the best days of my life. He takes care of me, stood with me at my odds and happiness. I will always feel light when i talk with him. Days went and our bonds were stronger. We were always a long distance couple, but never missed out on anything. We both trust each other and stay loyal. To be honest i know for sure that i will never ever find a love in any other guy like i do love him. It’s literally impossible to think. But recently we had some arguments regarding religions. We both don’t belong to the same religion. I am not an extremist in terms of religion but I love my religion and have a strong faith. Recently we started arguing but we try to talk it out and back to normal. Recently it’s little more. We never talk ill of each other religions but mis communication happens mostly. I am yet to tell my dad about this relationship but he told his complete family about it.i dont know how to make it happen when i couldn’t get the clarity of whether i am gonna be happy about this decision.
