Are you willing to chance religion so that you can get married?

I'm just curious and same time wondering why some agreed to chance religion or take the religion of the person they love and want to marry so that they will going to get married. I only have one question in my mind. Does it mean you love you God less compare to the love that you have with your husband to be or wife to be? Because for me no matter what will going to happen I will not going to renounce my religion and take the religion of a person that I love and want to marry.
