Husband left me behind in the dark

I'm sure I'm overreacting. I just can't help but be upset. Me and my husband were seeing some lights with our friends yesterday. My husband has a best friend and his best friend's fiancè was with us. We decided to also go see movie together. When coming out my husband saw something and started having a panic attack and ran to the car. His best friend ran after them. I was in healed boots and me and the fiancè are also both short so we can't keep up. The boys were smoking to calm my husband down when we got there. What happened was my husband saw his dad and his dad is an awful person who abused my husband for many years and harmed him any way you could harm a child. He's been N/C for 7 years now. Had I known what was going on, I would have just held his hand and helped him calm down but he took off running and then his friend ran after him leaving us both vulnerable. I'm trying not to be mad about it but the more I think about it the more fucked up I feel it is because he saw a dangerous person and then left his wife. I get maybe he wasn't thinking. I just always felt like a man is supposed to be his wife's protector and he failed me in that moment.
