#2 Let her know you’re interested in her. Talk to her, spend time with her, and let her catch you staring at her discreetly now and then. Make her wonder if you’re interested in her without revealing too much.
If you ask her out without making her like you first, she’ll lose the excitement of the mysterious relationship. Make her wonder what’s on your mind and you’ll make her fall in love with you without even asking her out.
