My OH has just made me feel like shit

I could cry.
Went out in the car again and he got frustrated with me when trying to reverse out of the driveway onto the main road. Kept telling me I'm making things more difficult etc.
Then driving in a 30mph zone he asks me "what the fuck am I doing?" cause I'm driving around 27mph (there was a police car so I was being extra cautious) he got me all out of sorts and I literally just wanted to stop the car and get out. I asked him what speed limit the road I was on was to double check and he said "your the one who's just passed her test and apparently knows everything". He basically argued with me sll the way there
I made him drive home, he's quitting smoking so he's snappier than usual but he doesn't understand that I'm nervous in that car, especially with my daughter in it, and the way he's acting is making me feel 10x worse!
