In practice, this looks like being happy, playful, flirtatious, and receptive to his advances. He must be the one pursue more of your time and attention while you allow and enjoy that attention.
When a man shows you he’s interested by regularly getting in touch and trying to date you, let him. Make him fit himself into your plans. Maintain your own life. Don’t suddenly stop working toward your dreams, quit your hobbies or make him the center of your world.
Also, have faith that the right man will eventually pursue you. Trust that if a man doesn’t advance toward you, he’s giving you a gentle “no” or “not right now” and let him fall away.
Stop trying to prove your worth or explain why you would be good together. The right one will be so captivated he won’t be able to imagine letting you go.
