<human>: My boyfriend and I have been best friends for seven years. We started getting serious about each other romantically a year and a half ago, and we've been officially dating 5 months. 
About a month after we started dating, he got a job as a host at a pizza place. Just recently, he's started going out every Monday night until 2 or 3 in the morning with the servers to bars and driving them all home once they're drunk. I HATE this. 
It worries me, for one, because I don't know if he's safe til he gets home, so I end up having to stay up late waiting to make sure. And worrying makes me feel physically ill. 
Second, I don't like what he's doing, the fact that he's at a bar, or the fact that he's hanging out with alcoholics. To me, that says a lot about his character, that I didn't see prior to now. 
I want a boyfriend I can be proud of in front of my family all the time. I can't as of now. I want someone who I think will be a good role model for future children. That's not him right now. 
I don't want to make him feel like I want control of his friends. He has some who I love dearly, but just not this group. I don't understand why these are the people he's choosing to spend his time with. 
He knew me first. He loved me first. He's got a whole other group of friends who are lovely people. I just don't know what to do. 
I can't say stop hanging out with them, but it bothers me so much I cant stand it. It really makes me question whether he's the guy I want to be with.

Give me the gist of the text in a nutshell
<bot>: I hate my boyfriend's new friends, and I don't know how to talk to him about it without coming off as controlling, because that's not my intent.
