Terri Schuester

Terri Schuester (née Del Monico) is one of the main characters of Glee. Introduced as the wife of Glee club teacher Will Schuester, Terri is portrayed as a rather self-centered and berating shrew, who will do anything in her power to keep her marriage from falling apart. This leads her to eventually fake a pregnancy and resort to other schemes to make her husband stay, but it is all to no avail. Terri later learns to move on and let go of Will, by moving to Miami.

Early life
Terri Del Monico was a cheerleader in her high school days, and presumably a popular student. It was in high school that she met her future husband, then-glee club member Will Schuester. They were together for 16 years and married for 5-6 of those. ("Pilot")
