You want new shoes? You buy them. You want to go on holidays? You book a flight. You want a man? You chase him right?
If you want a man, the last thing you do is go after him. If anything, this does more damage than good. Instead of running after them, let them come to you.
Biologically, men are hard-wired to go after what they want and they will stop at nothing until they get it. If you want him to come after you, think of yourself as the woman that they want not the one they run away from.
If you want him to chase you, remember that you’re the prize. View yourself in a different way. This will help you develop an aura of confidence that will make you a human magnet to your crush.
Lastly, try not to overdo it. If you let him do too much chasing then you might come across as snotty. It’s important to find the right balance.
