This story has haunted me since I read an earlier thread about it on MN. A friend of mine was almost killed by her then partner - she would have died without prompt, complex and lengthy surgery, but has made a remarkable recovery, mentally as well as physically.
There are so many layers to domestic abuse, from the sort of coercive control, that my father exercised over my mother as I was growing up, to murderous violence like this. The gaslighting, the threats, the dialling back ('I didn't mean it... I won't do it again...')
Spinal injuries are devastating, and Trudi will have so much to adjust to, and to mourn. She is being incredibly brave, and she will do an amazing job when she writes her book. EVERY young woman needs to be taught how to spot the signs that a much-loved boyfriend is a man who will try to control (and ruin) her life, who will continue to use violence to get his own way, who will not stop, who may try to kill her. I read Lundy Bancroft's book, 'Why Does He Do That', and it explained so much. Get your DDs to read it too...
OP, please pass on my good wishes to Trudi. She is amazing.
BTW, if anyone wants to help Trudi directly, there is a link at the end of the DM article. Being disabled is hideously expensive, and Trudi will need all the help she can get.
