Who is Thayer from She's Come Undone and what is their importance?

Dolores and Thayer meet in English class. Thayer does some repairs for Dolores at her house and eventually asks her out. When Dolores declines his regular invitations, Thayer asks if her refusal has anything to do with his size—he's a large man and has to duck at doorways. Dolores and Thayer later marry.
