I've known this girl since she was 6 years old. Now 11, with her toxic mother's attitude and way of thinking and her period. She's a blast. 
I have tried to get closer to her and when I do, bam something sets us back. I have two daughters with her father, then my oldest son who is 8 from my previous marriage. 
My SD has anger and aggression issues. She has no Emotional IQ and no empathy for others. I don't like having her involved with other family members kids because she will hit, kick, pull their hair or tease for absolutely no reason. Then wonders why no one likes her.
