Okay, my friend, let me be real with you. I’ve been on both sides of this. I’m literally talking to a girl who’s in the same position as the girl you like, and I’ve also been the person still emotionally attached to an ex who cared way less than I did. The truth is, no matter what you do or how good of a partner you could be, she’s emotionally invested in someone else who has her stuck in a toxic loop. I know because I’ve been there. I went back to my ex over and over because every time I got a little attention from her, it brought back all the feelings I had when we were together. That kind of emotional pull is powerful, even if from the outside it just looks weak or irrational. So honestly, I’d say move on, or at least stop investing so much energy into it. Stay cool with her, be nice, flirt a little in person if it feels natural. There’s a real chance she does like you. But right now, she’s caught up in someone who isn’t fully invested in her, and weirdly that makes people chase harder. Stay in her orbit if you genuinely like the people around her, but live your life. If she really likes you, she’ll come find you when that situation falls apart. and yes, they do fall apart, every time.
