ANSWER:
Don’t let such trivial matters ruin your marriage.
Now you’re married and this is your life, your husband and kids should be your first priority. Stop comparing your and his family, this might be the reason for the tension between you too. Look at the good things in him and compare him to other men who are abusive or disrespecting their wives!
Show him respect that he deserves and concentrate on your own household. If he divorces you, he can marry immediately as the supply is far greater than the demand and hundreds of women would love to marry him and make him happy instead of giving him a tensed marriage filled with sadness and depression.
