I really hope Ioan is able to keep the faith and keep fighting, even when Ella is lashing out at him, calling him abusive etc'.
She's doing what she needs to do to ensure her safety. The things I used to say to my father back then, still make me deeply ashamed. But, I would have done or said anything to make my mother happy while I was in her home, and attacking him was the only thing that did. It was the only time I felt any semblance of peace. It was never about my Dad. It was about keeping my mothers behaviour to a dull roar. No one that hasn't lived with a parent like Alice, can fathom it. You're forever in flight or fight.
Also, please get the girls cortisol levels checked.
And just incase he reads here ever, don't give up mate. Just keep loving them. I would be spitting venom at my dad with my mum cheering me on, and he would just say "Okay, love you. I'll be out the front to pick you up on Sunday." (And he always was). So I always knew I had a safe space with him, when I was able to. He never held it against me for one moment. And I was eventually able to choose to be with the one parent, who never made me choose.
Oh and also, I healed! So don't think that she has irrevocably destroyed your babies. I have a great life, I had pretty normal teen years, got a degree, met my husband who ive been with for 20 years, and we have beautiful children and a beautiful home.
I don't however, believe I would have any of those things, if my Dad walked away. So keep yourself in the picture. No matter what they say.
My mother is still miserable, busy making another man miserable, still goes off on rages about my father (who she hasn't seen since the early 2000's) and has never met her grandchildren.
A glimpse into the future for you dear Alice, if you do not stop this train you're on.
Everyone's ticket comes up.
