Totally correct CAFCASS will assess, see if son wants contact But at 16 it's very much in your son's power what contact he wants & how it takes place.
He may well feel relieved & not want contact at all. That doesn't mean that he will never have contact in the future. But that's up to him.
When my DS was 10, in a final hearing his father told the judge (we had a long drawn out contact court process -took 8 years) that he would rather not have contact with him if it meant in a supervised setting.
DS hadn't seen his father since his father attacked me at the contact centre & the volunteers had to drag him off me as punched me, broke my nose. knocked me out then tried to strangle me.
The Judge put it to him that if he was able to maintain supervised contact that it could be increased to non-supervised &, in the future, if all went well staying contact could be a possibility. His father said no to that.
Judge reiterated that if he said no on that day that would be it - no contact. His father said 'do be it'.
I was the one who had to explain all this to my 10 year old son (who wanted to see his father, but remembered how his father would follow us back to the car park & attack me) he wanted to see his dad without <as he put it> the violence & drama - just me & my dad he said. His father wasn't willing - he wanted contact with me not our son.
My son felt not wanted by his father.
This breaks my heart for only for my son. I understand what it is to feel rejected & not wanted by birth parents. Not being wanted is a bit of a theme in my family which seems to be based on adopted children..
My paternal grandmother was adopted,
I have an aunt who was adopted (my grandmother's grandchild brought up as her own child, but thought that her mother was her sister, but never knew it - (I'm still only of only 2 or 3 people who know it to this day) my brother & me were adopted.
I've always made my son know that he was very much wanted - at least by me.
My son said, so, my dad would rather not see me at all than see me in the contact centre. I had to say 'yes my love that's his choice'. My son said 'then I he's not my dad and I want nothing to do with him. My Gramps is my dad from now on. - I don't have any other dad'.
What I'm saying is that children see everything. Your son knows that you're being abused. It will benefit him for you to leave. GCSEs can be retaken if he fails. There will always be a 'reason' why now is not the right time You need to take action now. You need to do it before that man gets violent.
