So what do I do now that he seems to be ignoring me?

He has only a very casual interest in you, certainly not enough to pursue him, and for heaven's sake, do not stoop to playing childish games trying to make him jealous with fake pictures; he really could care less what you do, and now you need to let it go. If he wants to talk to you, he will, but don't be needy and desperate. HUGE turnoff.
