Sarah, what I am about to say is hard, harsh but realistic when dealing with PTSD. Besides that you need to look after you and bub first, your husband has an illness that he fails to admit he needs treatment and help for. If he loves you, and loves your child, then you have a drawcard if you want to pull and use to force him into help. Force is a strong word, and using yourself or child as bait is another, but the facts with uncontrolled PTSD is, we need to be pushed taking the initial steps.

I will say, obviously this type of tactic comes with risks, where he might let you both go... but by giving him options first, ie. get help or where both out of here (and provide an appointment already booked for him), then he might just pull his finger out and get help to save himself, save his relationship, and save his family.
