My friend, lets call her aimee, is my brother's girlfriend, my brother got it in and slept with another girl a week ago. i've known aimee since elementary and we hung out with the same crowd before and now we are seniors at our school, i'm closer to aimee than my brother, i don't like my brother but we talk sometimes.

i want to tell aimee especially since my brother didn't try to hide anything from me. and if she finds out that i didn't tell her she'll never talk to me again and we are like childhood friends.
