Highschool son has gone MGTOW

My 17 year old son is heading in the right direction. I'm proud to say that he is heading down the path of mgtow. He is currently in high school and just rejected going to a party because he was forced to be a "chaperone" for 3 girls while they get black out drunk and hoped to get with him. He said they were kind of upset and wondered if he "hated girls" and he told them that he doesn't and just wanted to hang out and be friends, but wanted nothing to do with being a booty call. They kind of got quiet and he said he could tell they were pretty upset. I told him he made the right decision and he said he felt like he just dodged a big bullet. He's going to focus on himself from now on
