I'm late, I'm also looking for advice, but I'm a girl so I got you
Try to make eye contact, don't look away instantly, hold it for 1 second and look away casually. Be confident in yourself, show it in your walk, how you talk, how you sit, because confidence does a lot. Also if you find any opportunity to agree with her, laugh at a joke she makes, or just talk with her, do it. Try to show her you aren't a jerk (I don't know you so I can't say anything about you) but one of the biggest things that will drive anyone away is to be rude, especially towards her, mkk well there's some advice, I hope everything's good and well by now but just in case 😊
