Why do many married men always side with their family and not their spouse?

ANSWER:

Good question, but I think not all married men do side with their own flesh and blood family, there are some married men that do and protect their spouses. But let me tell you why those men sided with their family, it could be that the trust, the bond, love, and respect they have towards their own family. To me its wrong because it says in the Bible, when you get married, your spouse becomes your family not your own flesh and blood relation. We will never know why some men do not protect their spouses and that includes the man that I married and his family..
