Morning thisis, I was thinking of you, hope you got some sleep and your Dd will be home soon!
Some advice from my experience, dont try to understand, explain, discuss or expect him to understand or want to, its all about him, all he can see is he is a wonderful dad, I am sure he loves them, but as an extension/belongining of him! And he knows a sure fire way to upset and control you!
As soon as you regain the ability to ignore him, you and your DC will be much better!! This is what took me the longest time, and still now I chant in my head "ignore ignore ignore"! It is wasted energy to try and explain to them!
I decided I was never going to slag their father off to my girls, but I also didnt want to let them think his behaviour was right or normal, I didnt want them to pattern relationships and men on him!! I also didnt want to let him carry on blaming me, he used to sit DD1 down and explain at length to her (she was 5 FFS), exactly how it was all my fault, how I had found anouther boyfriend and thats all I cared about
I had no idea how to deal with it or all the emotions and trauma my poor DD was trying to process (I still hate him for the nights she spent sobbing hysterically )!
In the end I phoned Women's Aid, I never had the courage to do it for myself , but for my DD I did, and am so very glad I did, they are wonderful amazing people, they helped me such a lot, my DD1 had a number of sessions with their youth worker which helped, they thought she needed a bit more support and referred us to the NSPCC who run a mother & child group for children who have/are living in domestic abuse situations, what a fantastic course it was!
I was very worried it was going to paint him as the bad guy and confuse her and upset her even more, but it doesnt, the children have a group together (usually 6-8), and the mums at the same time!
It really helped her....and me...in learning how to deal with him! They explain to the children, that its ok to love someone, its just their behaviour that you dont like! There is lots more, but it was a fantastic tool and even now I can use what we learnt there!
I really feel for you, I've been where you are and it was the very darkest time of my life, you can and will get through it, I can promise that!
Today my girls have gone off with their dad, both happy, I have a few hours to get some stuff done, they will be back at lunchtime maybe a little grumpy but by dinner we will be back to normal, its ok now
