If there is a more appropriate forum for this, please let me know.

In a relationship (or was??) with a person whose PTSD symptoms were profoundly triggered about 6 months ago. I am having a very difficult time in the relationship and have no idea if there even is a relationship anymore. She has completely emotionally disconnected from everyone.

I am committed to support her as much as I can and she accepts that support for whatever it's worth. I have been educating myself on what PTSD is, the symptoms, etc...and she is in therapy. I feel like right now, I have to emotionally let go of the relationship while trying to remain present and supportive so that she is not abandoned. I feel like I am being harmed more than I am helping her.

Can anyone give me advice, experience, or support on how to create and maintain boundaries that keep both of us safe? Is this even possible?

This feels like being in a tunnel with no light at the end, and if feels that way to me, I can't imagine how it feels for her. This has been so devastating for her, and I'm lost in all of it. I feel ashamed at not being able to do more and at expressing my own pain and loss.

Thanks.
