I would have to say No. A non believer would not pray with you. If you become one with a non believer your souls are joined. One of light and darkness is not fruitful. Pain and hardship will come. I married someone who just claimed Christianity. I was a young Christian and did not know there was a difference. He was raised in church I was not. The signs where there. I did not heed the warnings. I did not have a spiritual head of my household. Nor did I learn what Christ's love was like till the marriage was ended by his affair. I was brought down to his level instead of being lifted up. It is far easier for the darkness to pull someone down than it is for the light to pull them up. Stand on a chair, see which is easier, to pull someone up or them to pull you down. Everything requires food to grow. If you are feeding on the world, you will be worldly. if you are feeding on the spirit, you will be spiritual. What we surround ourselves with is what we emulate. If it is non believers, then we are more tempted to live like them. I believe the Lord had a reason for his warnings, and what he tells us. It is for our benefit not his. I would not date a non believer, and before I married, I would make sure his fruits are true. not empty words. We will know them by their fruits.
