I want to go to a concert without my husband
Why don't you want him to go with you?
He will just bring trouble to me, I just want to have fun without any hassle.
I don't think married couples have to do everything together. It seems all right to me to enjoy the concert on your own or with people besides your husband.
Oooh... I'll just leave him home.
As long as your husband knows that you are going by yourself that should be fine.  Just let him know in advance so that he is not worried about your absence, and so that he can find someone else to spend the day with.
