Me and my bf (16 years old) have been together 8.5 months. About 2 months ago, he met this girl let's call her *Haley* in his math class. My friends told me that he would always look and glance at her every day and when he answers questions in class he would look to see if she's paying attention to him. At first I thought boys will be boys. But then my friends ask me "why haven't you broken up with your bf yet? He cheated on you with Haley! He's been telling people he hooked up with her for the past 2 days!" when I confronted my bf he denied starting the rumors and his friend was surprised and said "wait i thought you told me you had sex with Haley?" and I left. i texted his friend who was there when i confronted my bf and he said that my bf claimed to have slept with Haley last Saturday night. Which i know FOR SURE IS A LIE because i was with him last Saturday night and Sunday morning. The entire night!
I found Haley through mutual friends and she said "your boyfriend is a douchebag. I'm not a slut. i wouldn't fuck him. We have never even hung out let alone had sex." apparently she called him out at lunch and my friends recorded a video to show me that she confronted him about the rumor he started. In the video my boyfriend played it off like he had no idea what she was talking about but then a random guy cried out "dude just admit it!" and the video ended. So I broke up with him.
I'm curious, does he or his friends think Haley is prettier than me? Why would he tell people he slept with HER when he never did? I feel like he thinks she's prettier because of the fact that he lied about sleeping with her out of all the girls at school he couldve lied about having sex with, he chose her. Did he make up the rumor to impress his friends and show them that he can get with such a hot girl? Be honest i can take it!
DONT ASK FOR PICS. im asking do you think MY BF OR HIS FRIENDS think she's prettier.

I am going to be a Junior in High School come this fall with a full schedule, 2 AP classes (why? I don't know) and an IB math course, along with Chemistry as my hard subjects. I've had to read a book that talks about how kids these days are overly pressured by the American education system and we are forced to "learn" through memorization and I can't help but to agree (I suffer from anxiety attacks which causes my brain to practically shut down from stress). My question is: Do you agree with the drastic changes in curriculum and policy within these past couple of decades? If not, what is wrong and how would you change it? If you have evidence, please include it in your opinion.
