You don't. Messing with other people's relationships is cruel. If your best friend and someone else who's in a relationship are "meant to be", they will work it out themselves
To break up with a guy who is your best friend do this. Talk to him about the matter. Tell him the reason and stop talking to him.
You do not make a couple break up and if you try then you will end up the fool. If you are trying to break up an ex boyfriend or ex girlfriend from their new love then by trying to break them up they will just detest you in the end. It is best to move on and if you are meant to be together then you will be.
support them both
First you have to answer the question who do you like more your best friend or the guy you like. If you break them up you have to lose one of them preferably your best friend. To break them up you have to tell your best friend all bad and suspicious things that her boyfriend does. But don't make it obvious that you want them broken up, just be as causal as you can and sneak it into the conversation.
To break up with your best friend's brother do this. Talk to the brother about this. Tell him that you are not interested in it anymore.

Well try to compromise and ask him why he is trying to break you guys up.
you need to be able to help your best friend if it's hard and stand up for them.
You don't unless you break up with your boyfriend
