We have a saying here... take what you need and leave the rest. This is a public forum, so you'll always get a variety of responses. Also, sometimes when our emotions are high, or when we're reading instead of listening to tone and inflection, we'll take things the wrong way. Don't let that discourage you.
I think the sentiment was "don't be angry at your husband, be angry at the PTSD". Some people feel like that, and use it to get by.
Like they have their wonderful partner and the the PTSD beast in them too. Personally, I feel like the PTSD is doing horrible things to my vet, but I don't think it's wise to separate him from the disorder... like he's only sleepwalking or something. It's him with PTSD. He's not only PTSD, and it doesn't define who he is... but he is definitely wrestling that lion enough that's it's part of "him" now. I guess it's hard to explain in text... but you get the drift.
You're allowed to be pissed off at your husband. He's not made of glass just because he has PTSD. Your emotions and mental health are just as valid as his. You're also allowed to be mad about suicide attempts.
