I also understand that I'll never know what my isolator (combat vet) has been through. I have my really bad days when I get mad at him and want to write things to him about how I also have needs, but I switch off my phone and go for a walk. It is so so difficult. When he did it the first time I had such a bad reaction to the isolation (few days) that it shocked me and I went back to therapy. Luckily I did not tell him about my reactions or lash out at him. I kept it to myself, thankfully, because at that point I was uneducated about PTSD.
Each time is tough, he always comes back, but is just unable to accept he is even doing it. We have a long way to go. The timing of the recent bout just sucks though. I'm trying my best to remember it is not all about me, but this time I'm in a low place (and he is not even aware of what is going on in my life right now because I don't want to add to things), so it is feeling more personal.
