It's disappointing when we reach out to people and they don't quite get it. I'm glad that you can see she is a wonderful friend, even if she's not able to really support you on coping with the effects of the abuse. I've had some similar experiences, and it really hurts when you want a friend to understand and they don't.

One of my friends doesn't quite get the dynamics of what happened or the symptoms I experience today, so to avoid feeling misunderstood, with her I will talk about "feeling panic" rather than getting into the specifics of a flashback or something. This way she can give me support--meet up with me so I don't feel alone, or chat with me on the phone until I feel calmer. This way, I get the support she can give without feeling hurt by what she can't give.

Stumpy makes a good point that maybe you guys missed each other...maybe initiate another conversation, or ask her if she felt uncomfortable when you brought it up, and talk about what you do need to hear when you can share. Good luck!
