My brother bugged me for six months to set him up with one of my single friends. So I finally set him up with my friend Ashley. They went out on a few dates and hit it off! I was so happy cuz I set them up! They’ve been dating now for a few months now and all seemed fine till the other night I came home and saw my brother saying goodbye to some girl! Obviously not my friend, his girlfriend! I asked my brother who the heck it was and he said, “she’s a friend.” I know she wasn’t just a friend. Our parents are away and they had the house to themselves. I followed him upstairs and annoyed him till he told me she goes to his gym and they hooked up. He told me that I better not tell his girlfriend. So now what do I do? I set them up and she’s a good friend of mine and if it was anyone else’s boyfriend I’d tell them. But it’s my brother!
-How do I get her to find out without my brother knowing it came from me?
-Who do I stay loyal to?
