What does the Bible say about marrying your ex brother-in-law?

In The Bible, marrying your ex brother-in-law is addressed in the context of levirate marriage, where a man is expected to marry his deceased brother's widow to provide for her. This practice is mentioned in the book of Deuteronomy in the Old Testament. However, the Bible does not specifically address the situation of marrying your ex brother-in-law in other circumstances.
