So recently one of my best friends broke up with his girlfriend, ending a four year relationship.........which is a pretty damn impressive thing as far as i'm concerned. Not ending it the fact that it lasted that long......but he started developing feelings for my little sister. At first he said nothing would happen unless I gave the ok and at first I told him no. Then I talked to my little sister who admitted to developing feelings for him, and how she was confused as to why she thought he liked her but he wouldn't do anything........so being the overprotective younger brother I start feeling like a jerk because now I know letting him act on his feelings would make her happy.......so I told him it was ok as long as he didn't hurt her.........now I don't know what to think about the whole thing......he started talkin bout how well she can bite a neck and I smacked him upside the head cuz I don't want details......all I want to know is whether or not something happened cuz it shows honesty, but just leave it at that.........am I wrong for looking at it the way I am? They're both happy but i'm all confused cuz I didn't see it coming till he ended the other relationship
