Lizzie Young is your ex. You two broke up after she started pushing you away after her sister died. You tried helping her but she got meaner and meaner to the point you couldn't take it anymore, she wasn't even speaking to you anymore.

Now you're with Katie, but Lizzie is jealous. She's especially jealous now, watching as you have your arm around Katie as you sit opposite her at her house. It's a group gathering so everyone is there but Lizzie is only focused on you and you're new girl
