She is behaving the opposite of how she was before H left, and is consistently rude, taunting, oppositional.
I find myself constantly wanting to tell her that she is behaving just like her father i.e. she has taken to lying bald-facedly to me, avoiding responsibility for anything, failing to do school projects, and so on.
She knows just how to press my buttons and I have ended up yelling and saying some horrible things to her in the heat of the moment.
I have displaced my anger towards H onto her, I know. And I am so frustrated to see her starting to behave in these ways.
Like you, I try to apologise and explain my lack of control. She simply sneers at me and says "I'm not listening to another lecture".
So, I still haven't worked out how to control myself or to communicate in ways that work.
But to hear from you, in such an open and honest way, about the problem is something that has helped me enormously.
I thought i was just so damaged to be behaving like this toward her. No excuses, I know, but being able to talk about has help me already.
