In Fable II, it is possible for the player's character to get married (including same-sex marriage) and have children. Divorce with the player's spouse can occur, and can be initiated by either the spouse or the player themselves. As with a real family, time spent around and interacting with them will keep the bond between them strong and reduce the chance of them leaving. It is also possible to become widowed through the death of a partner.
The relationships, as in the original Fable, are initiated by flirting, gift-giving, and the common expression. By performing a potential mate's favourite expressions, or giving them their preferred gifts, they will become infatuated more easily. Beyond a certain level of interest (or payment, in the case of prostitute characters), a character may proposition the player for sex. Unprotected sex may lead to the birth of a child, but can also lead to sexually transmitted disease, this does affect the player, may lead to sterilization. If the player has purchased or found a condom, they will have the option of protected sex. No sex is actually shown, the screen is black when the option is selected.
