Wibbly, thunder and everyone else, thanks for the lovely comments. If it's ok I'm going to ramble a bit more. Might not make any sense, but having nothing but time and thoughts to deal with today, I'm realising some things from reading others' posts, which I'd not considered before. It's pretty eye opening.
I always felt that my dad was the problem. He's a mean, nasty bully of a man, and my mum has always been, in my eyes, a weak, timid person when it comes down to dealing with him. I never blamed my mum at all growing up - my fury was directed solely towards my dad. I always saw my mum as basically a good person, kind, loving, selfless, and had been dealt a pretty shit hand being married to my dad. I could never understand why she didn't leave him, and that would be the only thing I blamed her for.
Since I had my DD, my feelings towards my mum have changed. I simply cannot fathom why she stood by and let my dad treat me the way he did. She even 'joined in' dishing out punishments to hurt and humiliate me as clearly I deserved it in both their eyes. I never saw her as an enabler before, but I realise that's exaclty what she has been. All my life.
I think I'm torturing myself a little as I know them both inside out, so know what will have been happening since I walked out 5 weeks ago. 1st, my dad will have been particularly abusive about me, face purple with rage, ranting, ripping me apart and 'cutting me off' from 'his money'. My mum will have been in tears, with the 'why is she so cruel' bollocks, despite the fact she's had the chance to speak to me to sort things out. And by sort things out, I mean accept that things as they were will no longer continue, and changes will not be modified to suit her or my dad. She'll have been phoning up her DS, SIL, friends, cousins, neighbours, getting all tearful and 'woe is me' about how she has such an awful DD who is 'using her GC to hurt her'.
I'd love nothing more than to have my mum see DD on her own, spend time with her, so they can both enjoy each other the way they always did. Without my dad around, she's not abusive, or nasty, or a bully, or puts DD down. But she won't do that as she's too loyal to my dad. She won't do that as she'll be getting shit from him about how she shouldn't be 'pandering to me' by doing what I ask. She's also dependent on him for transport, money etc. so he can quite easily make it too diffcult for her to actually see DD as well.
There just isn't an easy fix to this, but my resolve in protecting my DD won't waver. I'm angry that I didn't feel able to stand up for her when it mattered, and that I allowed her to be subjected to the crap my dad dishes out. I knew deep down things weren't right, but because I didn't see much with my own eyes, and what I did see I corrected, and stupidly thought that was enough to get him to stop, he's taken so much of her confidence away. And I've done it too - been 'harder' on my DD in an attempt to stop them jumping in and shouting at her too. I'm such a fucking idiot for not seeing what that was doing to my DD.
It was such a toxic situation, and only now I'm out of it, can I really see what was right in front of me. I won't repeat that ever again.
Now, I just need to get on top of things, make life better for me & DD, and hopefully fill in the lonely gaps with something else that will stop me feeling all 'woe is me'.
