Although modern relations between boys and girls have become simpler and more equal, some unspoken rules are still observed. So, it is believed that a guy should invite a girl to the first date. If your chosen one does not pay attention to you, then you should help him a little and make him want to ask you out on a date.
In order for such a desire to appear in the person you like, you should get to know better and interest him in yourself. The most proven and reliable way is to talk to him about what interests him. To do this, ask those people with whom he is close about his hobbies. Check out these topics and contact him yourself for advice on this matter. Such interest will be quite natural for him, because he is passionate about this subject, so you will not only have to listen to the answer to the question, but also ask him a few more clarifications. Ask his consent for further consultations, and he will soon, of course, pay close attention to you - after all, it is always nice to meet not only a like-minded person, but also a nice girl.
If you haven't been able to find out anything about his hobbies and interests, think of another reason to contact him. It should be a completely natural way to get his attention - ask a question about his opinion on something - the latest movie, a computer game, a performance by a musical group. Support the conversation by listening to his opinion and showing how interesting it is to you and coincides with your thoughts. But do not rush things, perhaps this technique will need to be repeated several times so that he finally discerns what a treasure you are and how interesting it is with you.
If you have known each other for a long time, but he does not notice your interest, try to take the initiative yourself - ask him to walk you home or just take a walk because you are in a bad mood. Find a reason to be together, ask him for help in something. Try to tell him something interesting that can draw his attention to your person. But don't forget that your goal is to get the guy talking. Let him speak up and encourage his jokes, be just a pleasant companion and the young man will want to meet with you more than once.
