If I may, I'd like to share some thing with you.
My very best friend and supporter hasn't been my room mate since the 1990's. I had an exacerbation and she'd never seen me act that way before. A major PTSD episode (exacerbation) can really do all sorts of things. Anyway, the thing I wanted to share with you. I had an Ah Ha moment a second ago.
While I was in that "fit", I told her she needed to get out. It's not because I didn't want her around, it's because I was afraid she'd get hurt. Physically hurt. Not by me, but by what was causing my "fit". She didn't' understand and told me she'd stand by my side through whatever I was going through (sound like some of what you guys say to your person?)
I knew she meant it, but I also knew the real fact that my ex-husband would hurt her to get me to do what he wanted. So I tried very hard to get her to hate me so she'd leave. But she still wouldn't leave. Finally, she called our religious leaders to help.
I won't go into what happened, but lets just say I was the one who left and she moved back to Washington State to live with her daughter. Over the years since then, we've been in touch, and when she's in the state where I am she comes to visit me. And in the past when I was on vacation, I'd go there and stay with her. We are best friends, but there is no way I can be living with anyone unless I'm together.
Perhaps your sufferer feels that same way. They are afraid they might hurt you (for those who have been in the military). When you'd been involved in murder, it is very real when you are not yourself, that you see someone else in place of the one you love and care about. It is not their fault. It is just a fact of PTSD. I"m sorry to be so blunt, but I'm just letting you know a reality that perhaps you are not aware of.If they loved you before, they still love you, but perhaps they are afraid for you.
Sometimes, a time apart can really help a person with PTSD to pull it together while they are getting help to sort things out. Then, once they've learned how to handle things, you can be together again. Thank you for listening.
