I'll take that as an honest acknowledgment that your religion is in error...But to answer your question, you go to Paul's epistles which are the books given to Paul by Jesus to present to His church...
1Co 7:27 Art thou bound unto a wife? seek not to be loosed. Art thou loosed from a wife? seek not a wife.
Are you divorced, seek not a new wife...
1Co 7:28 But and if thou marry, thou hast not sinned; and if a virgin marry, she hath not sinned. Nevertheless such shall have trouble in the flesh: but I spare you.
If you marry a new wife, you have not sinned...
Not hardly.
