I know you may hate it at first, but just try and get along with it as best as you can, cause either you get mad and let them know how you feel and they get upset at you and a possible friendship is lost and she dates your brother so she'd be over your house anyway, just not hanging out with you.
OR.
You could let them be happy, you guys still hang out, then they can hang out, and you guys could even all hang out together and it all works out for everyone.
You just have to put yourself in your best friends shoes. Say if she had a brother and you really really liked him, and he liked you back and you wanted to date him and your best friend just came along and was like,"NO. YOU CAN'T." you'd probably get sad and upset, right? And I doubt you'd want that to happen.

Anyways, they ended up going out, and it really pissed me off to the point where me & him were fighting all the time, & I ended up shutting her out of my life. I'm still not friends with her to this day.
Anyways, try to think of it this way. You want your brother to be happy right? Well, this will make him happy, so even though you hate it, let it happen & back off. I mean, there's going to come the day where you like one his friends. Just let them be together, & eventually you'll be okay with it.
