Hi Dsoda.
I think it was very brave of you to bring your husband; and I'm sure you had expectations like "he's finally going to understand exactly what I'm going through" and unfortunately the opposite happened.
However, have you thought about how he might have been feeling at the time? I'm sure he must have felt even a little bit uncomfortable, and people often have a knee jerk reaction to feeling uncomfortable in strange surroundings, either ridiculing or belittling something or someone that they don't understand.
From the way you describe him I would bet that if he had known this girl personally for the last 8 years and seen first hand what she had been through he would have reacted differently.
