Me and my husband were... being intimate last night, and right in the between, without warning, I switched. Sarah came out. I had no idea.

After the fact, Sarah was acting petrified so I asked her what was wrong... and she told me what happened.

Now, Sarah is scared of my husband (she is only 13 years old)
My husband has apologized to both me and Sarah, but it hasn't helped Sarah. She is still scared. She tells me she feels dirty.
It has brought back lots of memories for her. She was up all night last night with her thoughts/memories.

Has anyone else ever experienced something like this? How do you cope? How do I help Sarah reliaze that he didn't mean to hurt her?
