How do I make my friend break up with her boyfriend?

I have already told my friend to break up with her boyfriend but she just doesn't listen to me. She says she relly loves him but I don't think that they belong together because she is way to popular for him because he is just a nerd. What should I do. She allways listend to me but not this time. Should I just break them up myself. Every time I see them together it just gets me mad because she can do much beter.How do I make my friend break up with her boyfriend?

Leave your friend alone if shes happy with him don't ruin it for her. who cares if he isn't in your crowd. Like they say opposites attract and you try break them but karma will only come back and kick you in the but just be happy for her and be a friend and leave it be
who cares if he's a nerd? if she loves him then he loves him. you can't do a thing about it.
Well to be honest, I think you are a cold hearted b****. But that could just be me. I think you should let your friend run her love life. Don't try to help.
