not shamed but quieted

my boyfriend doesnt like heading about my traumas. I dont blame him, I couldnt imagine knowing somebody I'm in love having gone thru that kind of pain . I understand not wanting to trigger me, but when I have triumph moment and can say a traumatic moment without being triggered I get proud. I feel like I'm overcoming. he hates to hear it no matter what. I'm not really looking for support on my side, I know I'm in the right. I just want some help to understand how to handle his hurt better
