Nicolette, I think it's difficult to understand PTSD in itself. It's even more difficult to understand how PTSD manifests itself in the person you are caring about. Then it's difficult to work out what works for the sufferer.
With a cold it generally affects everyone the same way (assuming the same strain). Sore throat, runny nose, fatigue. And the same solution; bed rest keep your fluids up.
You might be an expert on PTSD, but then you have to become an expert on how it affects your loved one.
You only have to look around this site. Even amongst sufferers there are disagreements on symptoms, attitude, treatment. There are common themes of course.
But there lots of causes for PTSD. Each person has their own unique personality. Their own particular upbringing (I'm sure a PTSD diagnosis is compounded by a negative upbringing), cuurent support & stresses etc etc
But perhaps I'm going off track.
What I was trying to say is that PTSD is a disorder that affects the person. It is not the person. No more then cancer defines a person. Of course cancer is going to affect a person's behaviour from time to time. It would be understandable if a person suffering cancer was short tempered or rude.
But if a cancer sufferer was abusive and then said sorry I was abusive, I'm sorry I slept with someone else - the cancer made me do it?
Well I would hope that I would be saying 'if the cancer is making you do it, until you get help for your abusive behaviour I can't subject myself to it'
The individual is responsible for owning their behaviour (even if PTSD related) and taking the steps to get better. It must be so difficult watching a loved one (I've been on the other side with a relative with bipolar) and the word to sum it up is - helpless. It's an awful feeling of helplessness watching someone you love be in so much pain, but it's not an excuse for them to put you through pain.
:clap:Sometimes I even think the word 'carer' implies too much responsibility, and think maybe 'supporter' is better.
