Answer :

In the name of Allah, Most Gracious, Most Merciful
Assalaamu `alaykum waRahmatullahi Wabarakatoh
According to Shariah, it is Haraam (prohibited) for you to have any relation with this man as he is a stranger. Your concern for his guidance is understood however this concern should dominate you in such a manner whereby you violate the Laws of Shariah. Your concern for his guidance is motivated by your desire to marry him. If you are concerned for people's guidance then why not worry about the million men and women who are astray? This is the deception of Shaytaan. He intends to lead you astray in the name of guidance and Imaan. You should not pay any heed to this concern as you would be indulging in Haraam and committing a sin.
Furthermore, if you have inclination to marry him then propose to him in manner which is acceptable in Shariah and perform nikah. You state that he is gone far from Deen, then did you really consider your future with such a person. Will he take you closer to Allah or take you away from Allah? Did you consider your the implications of your Deen if you marry this person? If you have children from him what would be their future with him?  
Therefore, look for a suitable partner who is Allah fearing and conscious of Deen and perform the Nikah as soon as possible.
And Allah knows best
