hello whill. welcome to the forum. sorry for what brings you here, but glad you are here.
i am the ptsd victim with violent tendencies in my marriage. i am also a u.s. army veteran and have provided therapy support for my fellow vets with similar tendencies. in my logic, violence is understandable, but far from okay. the violent explosions are an unwelcome fact of my life. under no circumstances is it okay for me to explode at innocent bystanders. allowing one of my support peers to hurt me is far from helpful.
safeguards are a critical element in providing therapy support of this nature. let us not mistake gunpowder for black pepper. among my safeguards are 1) backup. i look for a trusted supporter who is apprised of the situation and ready to provide support, if needed. 2) escape routes and resources. i keep car keys and lodging funds ready to grab as i run out the door. 3) personal support. providing support is hard, mind/heart-bending work. having a shoulder to cry on helps me through. 4) stay away from lawyers. they have a way of turning incidents into judgemental, irrefutable history.
but that is me and every case is unique.
steadying support while you find what works for you. welcome aboard.
