<human>: Can you give me the gist of the text in a nutshell?

Him and I have been together for 4 months, he's hung out with some of my friends and I quite a few times. There are two girls who are close friends of mine who say mean things about him, he has a bit of acne and they make comments about it right in front of him and I know that he's insecure about it so that makes me upset. I'm very attracted to him and I don't care if he has some acne, and their comments bother me but I don't know what to say to them. They say he looks gross, ask why I'm dating him, if he even washes his face, etc right in front of him. I just laugh it off and pretend that I don't care if they're saying that. I think that they think it's funny, they say it in a joking way, but it makes me upset and I'm sure it hurts my boyfriend so I want them to stop. They've been doing this for a few months though and I think that they think it's acceptable or fine to do now, since my bf hasn't said anything to them about it bothering him. Should I say something? If so what should I tell them? I'm not good at confrontation.
<bot>: A couple of my friends make fun of my boyfriend for having some acne, they've been doing it for months and I want them to stop.
