Overreacting DH

Hey Everyone

this is the first posting and just needed some advice

We are due to go on holiday in a couple of weeks. My DH had his hair appointment booked in today so I decided to take the DCs to the playcentre. I’d accidentally taken his car as that’s where the car seat was and my car is so unreliable at the mo. While at the playcenter I had my hands full obviously crying DCs for whatever reason but my DH had called 20+ times and then when I returned his call he was just shouting as he’d missed his appointment. I apologised took both DCs home in tears so I could take him to his appointment. I was at the house 15 minutes before his appointment and it takes 30 minutes to get there. anyway he was walking out of the house and just walked straight past the car in anger. I drove to the house took the DCs in and while I was giving them lunch, he came in and went straight to bed and has been laying in bed for the last two hours. I’ll obviously get the silent treatment for a few days but I do admit this was my mistake but is this an overreaction?
