perhaps this is the unpopular answer, but i don't think it's your job (or best interest) to concoct ways to orchestrate the advancement of your relationship with him.
if you know him in a group/social way, and have had opportunities to spend time with him, and he knows you are alive, exist, and are available, the ball is in his court. hopefully, you have exploited these opportunities to ask him questions, share interaction, and listened with interest so that he is aware that you find him interesting and worthy of your attention/focus. you don't need "alone time", or even a lot of time to do that.
you don't know what is going on in his head, his life, or what his priorities are. you don't know if he's interested in someone else right now.
would you rather be responsible for "orchestrating" an opportunity to "trap yourself a man" or be pursued by a guy who finds you worthy of his time and interested in learning more about you?
by the way, i was totally joking about the "trap yourself a man" comment, but seriously, it's always my experience that:
1) you're always best allowing a guy to pursue you, because the timing is right--he's acting on what he wants, and you are assured he's not distracted by a different/peripheral option. women who throw themselves at men forfeit that luxury.
2) if he's a guy that won't pursue, it's either that he's not interested in you, or he's isn't able/capable of taking action on his own --neither of which makes him someone who you should be wasting your time holding out for.
i don't ask guys out. i don't try to "set scenes" up. i don't orchestrate scenarios or perform cartwheels so that he will notice me even more. i just am myself, but use the chances i get to learn more about him, asking questions, and building rapport. that's it.
i know everyone won't agree with me, but if you don't believe that you are worthy of being pursued by a man who finds you to be attractive and worth getting to know better, what does that say about your view of yourself? or his ability to discern what is attractive to him and acting upon it?
