As a rule, you should start to be a gentleman, try to please the girl, and do not forget the flowers🌼. But falling in love with a girl, first, understand what "falling in love" means. What do you want to get? Do you want a girl to be your life partner? Or do you just want to "fall in love" for once? A consumerist attitude towards women, like life in general, will lead to nothing good. Beyond that, we want to kindly remind you: There is no winning love by force. It's an axiom. "Getting a girl to fall for you" by force is impossible. You can only charm, please, interest. But if, after all the efforts, a girl is not interested in you, there are no options - you just have to back off.
