Hey so I'm a junior in high school and met this girl. We talk sometimes and she invited me to sit over with her one day when there was a substitute teacher in one of our classes (assigned seating). That day we talked quite a bit and she definitely seemed into me with kino, flirting, teasing, etc. and I invited her over to my place to smoke weed after school ( which we both do) but she cancelled because she didn't have a ride but invited me over. Problem was her mom and brother was home, plus she lived far and an uber would've been pretty expensive. Anyway, a couple days later I hear her talking about how this other guy (who is somewhat overweight and has long unkept hair) and her are a thing but the guy doesn't know it? She said this to her friends and knew I could probably hear her. I'd say I'm pretty attractive, as I work out pretty consistently, know how to dress, confidence. Anyways we Snapchat pretty often and she shows IOIs sometimes. I invited her to a concert and she said she had to work that day. Should I just give up and move on? Just irritating because I hate playing games either she's interested or not.
