How should I handle this situation with my boyfriend of 2 years? He is getting in with the "wrong crowd"?

"he is unfortunately very impressionable" He was going to dump his mom for his new friends and you, this weekend, of course you know that anything that was private between you and him is now public fodder to boost his new fame. "These boys are awful." so is he now! at-least he thinks he is. He don't realize that he is being used and maybe he does, but he likes the fast lane and hanging with a bunch of jerks that want rides to school/work/football practice/**parties** etc**. They all use drugs and call me stupid b*tch. He has been taking up some of their jerk behavior lately too. Maybe planning on humiliating you and dumping you after a couple weeks. He already chose them over you and his mother this weekend. He is part of the in-crowd for now. You are going to have, to have him make a choice -You or Them - "I just need to get him out of this situation." You or Them?
