I’m not sure if you are just fighting people on here, or if you really are lacking insight into your daughters experience of her childhood.
You may want to white wash the whole thing and declare it perfect with ribbons and bonbons and bows, but you cannot just wipe out her lived experiences because you say so. Or because you wish it was so.
It sounds like she had many great aspects to her childhood, and adults trying hard to give her as much as they had to give at those times. But she also had some significant life events which will have left their mark on her.
And by completely denying her right to have experienced anything but perfection, you may well be causing more of a problem than simply acknowledging these events.
Guilt can be a huge motivator, but it’s probably true that none of these things are your fault.
But the more you shout them down the more it seems you are on the side of the problems, versus the solutions... basically, I think you are missing a trick, and also digging yourself into a hole that doesn’t even need to be dug.
My last thought is that you do keep repeating this point about her having seen you cut people out of your life. You say you are proud of this but because you are repeating it, I think you do know there is a problem.
You may well have shown her how to be a strong woman who takes no shit, but you may also have accidentally left her with the fear that as soon as she pushes on those bonds of love with her mum, she will get the same treatment. This is especially likely in the context of her not having lived with you for a significant portion of her childhood.
Her attachment may well be a little more shaky, as she’s experienced being parted from her mum at a young age before. I’m sorry but that will be a part of her experience, no matter what the other factors involved and the overall good that came out of the situation.
No judgement here ok? Just looking at the circumstances and what children tend to feel.
Your DD is probably being an utter pain in the arse to test the fear she may well have. That the ‘unconditional love’ between parent and child isn’t there for her. That her mum has very strong conditions on her love, and if she pushes on those conditions, she’ll get quietly and coldly cut out of her mums life in the same way she’s seen you proudly do to others.
So being a fiery teenager she acts out to hurry it up if it’s going to happen, to bring on the tragedy rather than stay within the lines and have the appearance of unconditional love when it’s not what it seems.
Sorry all that may be horribly painful to read, triggering probably, but from what you’ve written about your daughters situation and past, and your own responses, that’s what I’m wondering may be at the bottom of it all...
