Relationship I really hurt a friend with PTSD, and I could use some advice

[joeylittle]

I can't really get away from the feeling that this whole thing my fault.

You aren't the rapist. So it can't be your fault. And your friend isn't the rapist either, so it's not your friend's fault.

The only person who can be assigned blame here is the rapist. Because everything else? Is a result of that event.
