Hope for anger issues

My husband has never hit me, or given me any indication of violence towards ME. However, when we have an argument that gets heated, he will punch or throw things around him like objects. It makes me nervous, and it makes me want to just leave the room. He gets upset when I do this because he says I am running away from the problem. We always fix it and things get better and we move forward. We don’t really have any problems besides this. Am I over reacting? I mean he’s not doing anything towards me, but just around me or to inanimate objects. He says it’s not normal for it to bother me that much and make me scared, to the point we’re I can’t talk anymore, and granted I DO have anxiety issues so I don’t know if it’s not okay for me to be nervous when he gets like that?
