Perhaps she does understand your efforts and so, she needs you to try to please her in order to confirm your love. Maybe her angst gets her the attention she wants. She is special, but not more special than anyone else. To me, she sounds selfish, and not in an unusual way. I wonder what you respond to the provocative questions. (and I wonder how the boys feel in all this.) It sounds like she's got you wrapped around her finger. I hope I don't sound harsh, because I think its your love that has put you where you are, and that where you are is, indeed, a typical place to be. Its not your job as a parent to make her happy. Its your job to guide her towards being able to find her own happiness. Be sure she knows that. At 13, she doesn't have that skill yet. It seems to me all you can do is repeat that you love her and are there for her. Tell her your rules about boys & the phone and accept her disapproval as her opinion. And stay firm, but kind. If she rebels, there should be consequences that are outlined 1st and carried through same as for young children (but more mentally challenging for you!) If she didn't challenge you that would be more odd than not. And also remember life, as well as parenting, is a journey. You won't "fix it" this week. You'll have ups and downs, make mistakes and get angry and sad. Just do your best, stay centered and be flexible so that the bumps in the road don't flatten you! I'm sure with your sense of certainty, she will eventually be certain. Good luck!!!
