She was, however there really was little indication of any residual effects of it throughout the 8 months that we were heavily dating.

I knew of the trauma because she told me, I knew what PTSD was, but I didn't know enough to pick up a lot of the little things that show she has it. Most of the major stuff isn't there, it's mostly little things...or the symptons come and go, but again aren't that pronounced.

At least on the outside. To her they might be, but she doesn't hold onto that diagnosis very much. I really think she had it firmly in check until her abusive Ex came along. Now the symptoms are slowly creeping back in.

It's tough to find out the boundaries when:
a) you can't really talk to her because she wants space
b) you aren't sure if she will take offense to being "labeled"
c) the severity of the symptoms make them seem nonexistent most days
d) she wears masks (like Anthony's post) to make everything seem alright almost all of the time

This is why I am trying to determine as much as I can from my own recollection of conversations, my own intuition, my knowledge of her and her behaviours, etc.

You have an excellent point though bec, and I appreciate it.
