you’re not “triggering him” he is being triggered.
THIS.
You are not responsible for the evils others have done.
You are not responsible for anyone else’s memories, or the way that they respond or react to those memories.
You are not responsible for how HE treats YOU.
By definition? If he is triggered? He is overreacting, and responding to the present as if it’s the past. Lashing out at you AS IF you’re an abuser from his past, a soldier he served with, a bit of wall that fell on him, or any other possible trauma? Is NOT treating you as YOU deserve to be treated. But as the abuser, soldier, or bit of wall deserves to be treated.
Repeat after me...
“I am not a falling hunk of rock. I do not deserve to be treated like a falling hunk of rock.”
Now try it with whatever his actual deal is. ((I am not his mother, I do not deserve to be treated like his mother. I am not an enemy combatant. I do not deserve to be treated like an enemy combatant. I am not a rapist. I do not deserve to be treated like a rapist. Et cetera.))
Because the key with boundaries? Boundaries are NOT “You can’t treat me like / You need to stop treating me like/ etc.” but “If he treats me like ABC? I will do XYZ.”
Sometimes? “Oy! I am not a rapist! Stop treating me like a rapist!”
will be the XYZ. Or just the X. As the Y is ‘leaving the room’ & Z ‘refusing to engage until they’ve pulled their head out of their ass’. Shrug. There’s no hard and fast rule for
what a boundary is... just how a boundary works. A lot of people get it backwards, thinking that boundaries are telling the other person what they need to do. Nope! You can tell the other person that if they’re going to be nasty you’re going to walk away... but the actual boundary? Is that when they’re nasty, you choose to walk away... Instead of accepting as if you deserve to be treated nasty.
