My partner went through something similar, and I’m really glad that they’re open with it. Obviously I would never make them go into detail, but the last thing I would want to do is do something that reminds them of their trauma. If you feel safe doing it and trust him, I would at least tell your bf any possible triggers/things that make you uncomfortable
Maybe hint, but don’t share too much detail. Say something like “bad past experience”. As an experiment, you could invent a trauma story to share that’s totally unrelated. Something like “when I was a kid, I crashed a bicycle into a hot grill and get flashbacks when I’m around bicycles”. Or something. Then see if he uses that against you. It won’t hurt as much if the weapons he uses aren’t real. Then once you know you can trust him, tell him the full truth.
