I just went through the same thing and it was awful. My 16-year-old daughter went to live with her dad, so I am definately not a perfect person but I will tell you that it does get better and this is the book that I am using to try and keep my wits about me. (so far, so good). We have 7 children in our combined family. I wasn't sure what to do and then I came across this book.
I am reading a book called The Surrendered Wife. Now I know you are going "What will that do for me?"
Funny I was thinking the same thing, I found it in the library and I picked it up trying to figure out what the title meant. LOL.
I have no problems with my husband (newly married again, that's why the title caught my attention).
Anyway, I started reading parts of it and recognized some of the things in it as to how I was treating my children and I thought I could use this in my relationship with them, and it's helping. ALOT.
What I am learning from it is that I need to learn how to treat them in order to get a response that I want from them and that how I make them feel about themselves is why they were acting the way they were.
I thought my job was to tell them what to do and they would just do it seeing as I am the parent, I am learning that although this is true, HOW I tell them is going to be what reaction I get back.
The book is really an easy book to read and although it was meant for marriages, I see where I have to change also, just like I want my children to change. If for nothing else it really is showing me that I was unintentionally pushing away my own relationships when all I wanted was the best for my kids. Now one is gone, and I refuse to let it happen again. I wish I could've had this book last year.
The great thing is my daughter and I have a great relationship now and I really thought it wouldn't be like this. I just know that I had to do something and this is what worked for me.
It also took alot of stress of me, I can't believe the difference. I have very firm rules and they live by them, like them even but they weren't treating me very well, and I believe that is because of how I was treating them and it just was too much tension in the house. I spent alot of time in my room just to stay away from conflict.
Good luck in your quest. Just by posting this here shows you really care to do something, anything, and that is a step in the right direction.
Sincerely.
