Is this a PTSD specialist by law enforcement. I am not sure if they have their own. I am assuming so. Though he may not want to discuss or lay all of the details of his work on you. It would help if you talk with his therapist also. They may have suggestions. Also seek out support of maybe forming a support group with other women who are wives of detectives or related law enforcement. If they do not have one, maybe you can suggest starting one.

Though you may feel helpless. When people have PTSD a lot of their feeling is denying comfort. Especially in this case. They may deny comfort when they see others without it, or hurt. It is them sharing in others suffering. It is a normal grieving our body does for others.

...but they need to be comforted. You need to comfort your husband. Hold him. Its possible he could release.

Its not a case if someone can handle it or not. Everyone is different on how they encounter things. ...and more perceptive and more sensitive people. Are going to hurt more. The gift comes with a severe consequence.

The best detective see more. When they see more, their going to hurt more. We see things in different ways. ...but a detectives job has to analyze things a bit differently and more closely. Also getting more personal involving the details in their lives and around them AND THEIR MINDS...

and when you have to deal with minds of mad men, and the innocent who are harmed by it. It is touch.

The less perceptive will be more assumptious. This is how they get bad cases gone wrong not properly investigated right. ITS A NOBLE JOB. ...its VERY DANGEROUS.

Not because of only physical threats or physical diseases....but the type that is not seen and can sneak up on you, and poison you, and threaten your own mind.
THATS WHERE THE BRAVE GO...that so many avoid going...

He needs to be held. If he refuses. Ease into it gently. Talk to him gently. ...BUT NOT WHAT YOU THINK YOU SHOULD DO OR SUPERFICIALLY!

A rub on his shoulders. Letting him know you admire what he does. Letting him know people like him are needed.

I cannot respond to the statement about him saying,"having a family makes it difficult going to an abused babies autopsy."

Because I do not have enough info on your relationship and your discussion about it. ...and how that is brought up, or if you now have children or not, or if future plans were discussed.
So I do not want to respond randomly to that.

I cannot say per-say that you need help. ...but maybe just a bit of support. ..and I would check out law related wifes and support to such situations. Maybe talking to someone on the force or calling someone anonymously to get info about it. ...Maybe you could seek out or even start a city support group for law enforcement wifes.

Just some thoughts...
