I don't know if you want info about trauma, general advice, examples of how I deal with C-PTSD in my relationship, or just support. I hope at least some of this will help.

What I Did:
I told my boyfriend on our first date that I had Autism and C-PTSD. I didn't give the particulars of my trauma except to say I had been in trauma therapy for almost 11 years at that point. He told me that he has Acute PTSD, and he didn't give many details either. We both just wanted to break the ice in a non-threatening way. It took several months of conversations and various steps of disclosure until I had told him my full story. I was terrified of being judged or alienating him. I also have a very difficult time with interpersonal relationships because of my damaged self-concept, which is a hallmark of C-PTSD. He is the only person apart from my first therapist and the court of law, who know exactly what happened for me. The process of sharing made me extremely vulnerable. I was scared I'd form a trauma bond and become too dependent on him, or that I'd love him for knowing -- instead of loving him authentically for who he is overall. My disclosures are still unfolding because we get very limited time together as a result of Covid.
I won't sugar coat it. It's a lot of work balancing a relationship where both parties have PTSD from violence and victimisation. He and I have different stories and different triggers. I tend to have "emotional flashbacks" (unexpected volatile reactions caused by feeling an emotion or sensation similar to those I felt during trauma), and he tends to have "visual flashbacks" (picturing or hearing the memory more literally). We're both mindful of each other's potential triggers, and we are still learning how to support each other through the dark days. What works for one of us does not necessarily work for the other. Some of our needs are in contrast, meaning that the support he needs sometimes triggers me - and vice versa.
Support for you:
Chances are your fiancée knows you have PTSD. You have survived the loss of your mother, the suicides of your cousins, physical assault and battery, plus the horrors of your Palestinian experiences. I think she is drawn to you because you both have lived such traumatic lives. The discussion of PTSD will evolve naturally for you both as you get to know each other's story in more detail. There's no need to rush or to force the issue, but do assure her that you are committed to the relationship and that you are seeking help. Reassure her that you're there for her when she needs support as well, and that way you will begin a two-way dialogue about the topic. Perhaps you could seek therapists together? I don't necessarily mean the same therapist, but you could help each other look for resources. I imagine there are mental health programs for refugees and victims of war or violence, where you live. Given your recent injuries and her recent PTSD episode, it should be easy to inquire with the hospital about trauma-related social services.
Best wishes and virtual hugs to you both.
