My sister, 15 years dating back 21 years, can you please give me some advice?

I have a sister aged 15 years and has been secretly dating the boy next 21 years HES. It all started since we moved here in the summer last year, changed his attitude, which tends to isolate himself from his family, and every time I communicate with my parents, it usually ends up in arguments. I am the oldest, I do not know what to do, because I am ashamed to recover all such things as, hidden outside the house at 3 in the morning and go to the house of the kids has pictures of him and hid him. it tells us nothing, but it obviously has some What happens to this guy. , And it seems every time my parents tell some advice, pretended not to hear, she still sees the boy, and no notes that say "I love you" of man. the guy just does not go to school. IAM very concerned about it, I do not know where all this is over.

You may be concerned, but Ultimately, it's not your problem to solve. This Just do what her brothers and born large for their parents. By refusing to cover, then place the ball in the field from their parents to strive to respond to most is his work, whether or not capable of adequately handling. You should not try to fight your battles for their sisters, but take responsibility for their own actions, or you can fight the battles against it all his life, which I think is a bad idea at the end. I know from experience. If your sister asks you to help pick up the pieces and then be there, but make sure they understand that collect pieces will not be a long life or yours if you end up doing all life as well. Your real job is to make you as good a person as you can and support the difficult decisions that their parents do. Not to be a father!
