Ask April was right about going to that restaurant again and again, but here I will also say that when you go there, go as if you came to buy that restaurant, not to ask for it back. Look sexy, feel confident, go with one of your “hot” friends, laugh with her, enjoy yourself, and completely ignore this guy. When he feels that your life is spicier without him, then his smile will be a little “nervous”. If he gives a cold response even after going again and again, then move on.
