Get back to what you are doing.
Perform it once more – one time.
That which you’re doing is providing a green light and by doing it a moment time you are reassuring to him that exactly what he saw actually occurred as well as your focus ended up being on him.
Beyond that – it is as much as HIM. Do not get too excited however because as you care able to see from most of the reasons in the list above – approaching a lady isn’t one thing guys do well at all and even here is another few times in their whole life time. (according to circumstances needless to say because where so when makes a huge difference on if he will come up to speak with you. )
