|Tammy to Ashley|
Despite her appearance, Tammy is a good-hearted woman, who knows how Alan feels about her and her relationship with Jake. They broke up, because Jake had sex with Tammy's daughter, Ashley. She found solace with Walden who could relate to failed relationships. As he was around her age, Walden was at her level of maturity which is why they were compatible.
