You're the oldest, She looks up to you, and sees the true best in you, even if you hadn't seen it in yourself. It will take an awful lot to loose her trust in you.(years of being lied to, and not following through etc...) She will watch what you do, listen to how you speak to others, how you let others speak/treat you. "attraction by actions,not lectures" Help build her confidence, and solidify her self-esteem, so she can survive like you;) Good job sugar. Do you know ways to boost confidence/ self-esteem?
Good Luck! CoCoCoMom.
