ANSWER:
Your in laws have no right in stopping you from going to your parents house or stopping you from anything. You don’t have any duties towards them, none whatsoever.
You’re only obliged to obey your husband. If he has no problem, you can go even if your in laws don’t approve of it. You are not their servant nor their property.
