		| Although people constantly search for partners, there are always some ones who are left as singles. This paper provides a simple model to demonstrate that this can happen even in the environment most conducive to partnership, when monitoring infidelity is not perfect. The intuition is that, when having a partner is preferred to being single, being single can be used as a discipline device to prevent infidelity. |
