Does your spouse ever scare you?

This may be silly, but today I asked my husband while he was laying down if he would mow the lawn and he said yes. So I went and got it out and put gas in it. So I go back an hour later and tell him everything is ready he gets pissed and says he was asleep and doesn't remember saying yes. I told him okay I'll do it and he gets pissed and starts looking for a shirt to wear. He starts throwing the folded clothes all over the room , while yelling "fuck you" over and over again... It truly scared me and then I told him he scares me when he gets this way and he told me you can't handle me when I'm at my worst, I wish you would have figured that out before you married me... Am I stupid to be scared of him?
