but who by worrying solve a problem?

Even the scripture says, who by worrying can add a year to his life? I can't vividly put that word together but something like that.

There are people who just want to frustrate us unnecessary, making us feel anxious and confused of what to do but in that moment, being calm to think straight matters. We can't get something done when we are impatient and also, by trusting God is important.

I believe your husband was just frustrated at that moment and with him calming down, things will take a different shift. We don't act when we are angry or frustrated because we would definitely mess things up. I believe everything will be sorted out soon and God won't allow him go the wrong way to complete his mission.
