the fear is so real...and i think I truly felt it's force once he's left. In fact I had full blown flash backs and panic attacks for a few weeks earlier this year....they too went. a sort of post traumatic stress i think..and also dreams...
Like the story...we can't go over it, we can't go under it we'll have to go through it...but on the other side is life in all its fullness.
With the DC: do talk to school to document what has been going on, be specific, ask them to watch out for changes in behaviours and to document well. Talk to your local refuge they may have some interventions that they can provide in school. have a look at women's aid website and especially show your DC the hideout it will help them process what they have been through and access support themselves also give them the number for childline 08001111 www.childline.org.uk/. Nearly all children self blame and having neutral people to talk to really helps them.
In my case I got social services involved, described the behaviours etc and they opened and closed a file. This means there is a record from BEFORE legal proceedings commence of my concerns and his history...thus CAFCASS have to access these and take them into account, not just my NSDH (not so dear husband's) view of himself as a parent and me as "mad".
My OH had a "psycho face" too...sends shivers down my spine just remembering. For this reason i will only communicate by non-direct means (text/email) and I NEVER reply immediately about anything. I always wait a few hours at least to take the heat out of the situation and assert my independence. he hated it at first and just plagued me with texts but over time he has realised he gets a quicker response if he leaves me alone (!!). I would never be this way normally but self -preservation is necessary.
Well done for reclaiming your life.
keep posting and please don't cover up for him, if people ask why you are apart tell them and take all the RL support you can.
