First , give her to God, pray for her and the rest of your family. She is entering her "teen " years, and you can remember what THAT was like. Also, perhaps now that you are her stepmom instead of her father's girlfriend, she has a lot more resentment toward you. You are now a permanent fixture in her life. You should have a t least SOME say in the discipline of this child. after all this is NOW your household too, and if she continues to disrupt it, it will eventaully affect the whole family. Perhaps, she enjoy's being a "drama queen" and is using it because it she knows it annoys the heck out of you. No more flowers, cause she sees this as an attempt to "buy" her love. Patience, Patience, Patience. Buy yourself and the boys some really good ear plugs, and let her yell all she wants! If Dad really wants to handle it let him! Ignore her attemps to tick you off. remember when you threw a tantrum as a child and when you got ignored , you realized you werent going to get your way? You quit, well, she wil too. And tell Dad, that he needs to quit feeding into her little tantrums too. I've been there done that wiht my stepgranddaughter. It took a little over a year, but she finally came around. Good luck! I'm praying for you and her!
