text: how can you tell if a girl likes you after you told them? i gave her a card for her bday and it also said i like her. she said thx. wtf does thx mean? thanks probably means that she doesn't like you and is just being polite, or there is a small chance that she is shy and doen't know how to take the next step. just talk to her, either you will get closure or she will love you for taking the next step for her
