In the United States, second cousins are legally allowed to marry in every state. However, marriage between first cousins is legal in only about half of the American states. All in all, marrying your cousin or half-sibling will largely depend on the laws where you live and personal and/or cultural beliefs.

Is it weird to have a crush on your 2nd cousin?

Khurki would say its perfectly normal. Remember having a crush on your cousin doesnt make you a bad person or freak. It happens at a stage when teenagers start developing feelings for the opposite sex and if you are happy being close to your cousin, it is okay!

Are 2nd cousins considered family?

Second cousins share a great-grandparent, either maternal or paternal. Understanding second cousins is much the same as understanding first cousins, except the family tree must go back one further generation. If members of your family were adopted, your second cousins may not be blood related to you.
