Yes. Many Sufferers have described being contacted during this time as extending the period they need to be alone. Let him come back to you when he's calmed down and can again have you in his life.
When he's stressed and needs alone time, he'll likely need to be completely alone, without you contacting him. When his stress cup overflows, he'll need time to let the stress subside and calm down before he can handle adding you back into his life. For the foreseeable future, you can probably expect this to get worse, not better, as it's often necessary for the Sufferer to disengage from the one they're closest to until the stress overflow subsides. I can't recommend the stress cup theory enough: The Ptsd Cup Explanation.
You're embarking on a difficult path and will have to understand you're never going to have a "normal" relationship. You can't have the same expectations you'd have with someone who doesn't struggle with PTSD.
It's not unusual for PTSD relationships to have the aspect of being the most intense, soulmate-like relationship ever. It's an intense roller coaster. There's a current thread discussing exactly this: In The Beginning..... I encourage you to read and participate in the forum. You'll begin to see the same story and patterns repeating themselves. I also encourage you discover what you're likely to experience in a PTSD relationship and to think long and hard about whether you have what it takes to commit to this process with someone. Loving someone with PTSD can be amazing, but it can also make you want to pull your hair out like nothing else.
I came here thinking the problem was him. I found I was as much a part of the problem as the solution. The changes I've seen thus far in my relationship have been prompted by me focusing on and changing my own behavior and letting him do him.
