Re: What would you do in this situation males and females?
He IS making his move - but he is not being honest to himself about it.
Personally I would agree with the other assessments to only deal with this person in public, and when he chases up tell him the attention is discouraged by your family (do NOT under any circumstances accept personal responsibility to say know, or bring God into it - the chap obviously has a "higher connection", which can easily start getting fed from darker parts in his psyche if he feels shamed or denied, and is just as likely to "receive encouragement from god" to pursue his desires).
He _might_ be nice chap. But on "hearing voice of god crazy people" he's already 5/6s of the way there. He has to get a grip on his own responsibilities in life, before getting so tied up in "taking direction from God" because God sure isn't going to be taking responsibility if the guy starts getting his messages mixed up. and he can take any polite request for space or delay as a personal contract !! Not uncommon for people who frequently outsource responsibility to third parties (be it God, Government, "boys do that", natural order, "The Law", "just business", "honor", "just common decency" or any number of other blameable authorities who don't get to speak on their own behalf).
If she does end up going out with this guy, expect a LOT more of "God's direction" for things. So really only good if they're both crazy in the same way and same degree.
