My brother's best friend want to be with me in secret?

Don't want to be frightened . just tell ur brother that u and tyler were together dat night and convince him . tell all the things dat tyler told u not to tell ur brother .Ask ur brother to find why tyler said to keep this thing as a secret ? .don't hide anything from ur parents or siblings. just be calm wen u tell ur brother n don't cry or do something crazy . ur brother can understand u very much ! n don't share ur feelings with tyler 4m dis minute . hope ur problem has a solution.
