Have I the right to be so mad my husband did not return home after he found out his little boy was injured he

My husband went down south on friday for the night he knew I had to work Sat night at 6pm. On the sat my son fell of his bike and ended in hospital I rang my husband he finally rang me back at 4pm he said he was 3 hours away! Now he knew I had to work at 6pm! And his son was in hospital! He instead went to the Dunsburough hotel and never came back home till 11am Sunday morning! He then caused an argument and left again he sadi I was over reacting?
