My problem is related with my in-laws, they interfere a lot in our married life. My husband has a very strong emotional bond with my mother in law. Due to this he left me with my son, and start staying with my mother in law. Please suggest me, how to handle such a situation.

Unfortunately, only you cannot solve this. Both of you have to act together. Such Interference is very common but couple has to jointly decide how much to take it. Take your husband in to the confidence and try to explain him that this is not against his mother but this is about your privacy. Rather than blaming his mother, try to establish positive communication with your husband.
