2. Flirt With Her: Try to spend time with her when she’s alone. If her other friends are with her, you can avoid her or just wave a hello and move on after a quick chat. The more you hang out with her as just a friend, the lesser the chances of you ever making her desire you.
Spend time with her only when she’s all by herself. That’ll give you enough time to date talk her and discreetly flirt with her. Flirt with her, make her feel warm and awkwardly nice while hanging out with you. And treat her just like you would treat your girlfriend, but don’t ever call her your girlfriend though.
