The thing with abusive dynamics is that victims are trained to do as they are told, in all things, at all times. If things aren't done in the right way they can panic. They are forced and controlled to beyond all limits while in the relationship. They are unable to have their own feelings at any time.
Abusers also change the rules from the frankly mad to the totally insane at the drop of a hat, yet we are supposed to know this in advance.
Remove the source of control and the panic sets in, we don't know what to do! the merest thing we can panic at, no knowing what we ought to be doing and our confidence is so knocked as to think that we can't do anything right anyway. there can also be erratic behaviour, ups and downs as we try to find our own level in all this chaos.
YOU have had issues in the past with controlling behaviour FG2B, you have not resolved those issues (it's OK, you've never had to) Now your DD is going through extreme violence, extreme abuse and threats and she is hormonal to boot. YOU (being a bloody marvellous mum) are trying to take it all away, to make it all OK for her, but of course it's not YOU that holds that key.
Your DD is learning to think again for herself, she is scared, and yes she too wants it all to just go away, she doesn't want to deal with any of it.
The feelings you are both feeling are natural, normal and tbh, if you weren't going through them tbh, I'd be worried.
her outbursts also mean that she is feeling able to express herself safely to you.
As hard as it is, don't panic yourself, stay calm, she's a bright girl, she knows what to do, she has great instincts and the FOG that this bastard has surrounded her in will lift for good eventually. I don't blame her for wanting to get away for the weekend, it's not you that she's running from, it's the fear and the mess that has you both all tied up in knots.
Who was that woman that talked to her before? when she came out of there she only wanted cuddles? remember? can you call her for some back up?
You know that you are not alone. Pick up the phone, call WA, you have my number too.
