Finally,
a good final test to see if you should stop pursuing a girl is to actually stop pursuing her, and give the chase a rest for a while. You might find out the answer you’re looking for. If she’s interested in you, she may try to find out where you’ve been. She might actually become more interested in you, because you’re not trying so hard. But you might also find that she doesn’t care that you’ve stopped pursuing her. That’s a good sign that you were pursuing the wrong girl.
Remember, not every girl is going to be attracted to you. But you don’t need every girl. You just need the one who will love you for who you are.
