Again I'm assuming based on what you said but it's really not worth it. If he can be mean to you just to keep his friends then he doesn't deserve you. Also (based on assumptions), you seem to be quite young as well so you'll definitely meet someone better in the future. Don't worry about stuff like that.
P.S. you should report bullies. Honestly, what they're doing is wrong so don't be lenient just because your friend is one of them. They need to realise that what they're doing is wrong but they won't until someone reports them. If they just continue the way they are, they can cause serious harm so don't feel bad or scared and tell your parents or your teachers. But someone needs to teach them a lesson.
