From what I gather reading your post on Friday, you are or have been seeing a guy of 21 when you are only 16, your sister reported him and you are not from the U.K (where the age of consent is 16).
You are young, very young, at the moment as this chap was your first proper love you probably feel like the end of the world, that it is so unfair and nobody understands how you feel, am I right?
Life will go on, you will meet someone more acceptable to your family, but it will take time
