If you really accepted that girl as your sister, then it doesn’t any matter whether there is someone other or not. You have some responsibilities towards your sister. So without any hesitation go and do it for her. You should guide her as a brother until her marriage (After that also you have some responsibilities to her). If you think that someone going to cheat her and try to keep her away from you, then you must talk with her frankly about that. That means ask her frankly is there someone new in her life, and if yes, try to get all about that person, about his nature, about his motive, and help her accordingly.
