DESPERATE for advice in a situation with my boyfriend is in the "wrong crowd"?

tell him what you told us today. Those guys are jerks, they will be working as bus drivers/cleaning the streets/selling fruits/construction worker very soon and your boyfriend needs to realize that they are loosers. You seem to be a nice girl, it's hard to find someone like you, with the feet on the ground. good luck. (Just in case he doesn't listen to you and maybe start to be a jerk like them, you are not married with him, you know...)
