The best bet would be to tell her to ask him what he feels about her. If he does not play any game and tells her everything sincerely then I guess things will get lot easier for your friend to decide. If the guy already has a gf then there is no point waiting for him. If not, then probably there could be other reasons like he might not be in a mood to marry. In any case, the girl should talk with him and see how it goes from there. Remember relations are like a fistful of sand. The more you want to grab it tight, the more it will get spilled. Let it be gentle and loose, things will be easier. Good luck!! Lonely...
