Hey josh listen to this. So my crush is this new girl at school, but at first I didn't notice her until she continually stared at me. I started to grow feelings for her over the course of the school year, but she lost interest in me. How can I turn the tables (get her to like me again, etc.)
The best way to get her to start liking you is to start interacting with her. If you start talking to her, flirting with her and even ask her out then you would have given her plenty of reasons to like you. Try not to rely on little things like looks and smiles, they're never real indicators and an indirect approach like that never quite results in the way you want it to.
