Do you believe Jesus when he said in John 14:6 "I am the way the truth and the light, no one can come to the father except through me. "
God will judge and throw everyone who has not accepted Jesus as Son of God and committed their lives to Him into Hell and lake of fire.
You have also been given plenty of verses and advice from the Bible as to what it means to marry a non-believer.
Of course at end of day you have free will to do what you like, but once you are married it will be hell, you will become second class and it would not surprise me if you are banned from anything to do with Christianity, your husband to be would not want to live with death threats for too long.
