The character is forced into a marriage that is not by his or her choice, is something they are opposed to actually doing, and would not consent to under normal circumstances. Reasons can vary between being sold into marriage against their will, parents forcing them to get married to someone (possibly under threat), or for some other reason.

This trait also counts if it was attempted but not successfully completed (such as the ceremony being interrupted for some reason). What matters is opposition to the marriage and being forced to go along with it.
