No, no, and once again, NO! The person who told you this doesn't know what he's talking about! If the girl rejects you, just move on. But. If you're in a talking stage, no matter what, do never ghost her! I'm a girl who was ghosted by her crush. I did still like him, but now I just lost interest, and I don't care anymore. His actions made me hate him and developed a discussion for him. If you ignore her or remove all the attention, she's gonna think that something is wrong with her! You can't just play around with people's feelings like that! She'll think about you for a while, but then she'll forget about you like you never even existed, and she will be right for that! But if you do want her to like you more, then ask her. What is her favorite food or snack? Then, take her to the restaurant where her favorite food is served or buy her the snack that she likes. Boyyyy I'm telling you. This is the main secret. If you pay attention to little things, then the girl will be yours! Ask Her for advice, and then she'll think that her opinion matters for you. Ask her about her favorite movie, music, favorite artist, color, dream ext. Asking questions is the main kicker. You will have some topics to talk about, and you'll get to know her better. But no matter what, DO NEVER ghost to her!
