First of all she dumped me 2 years ago. She lied, and treated me like complete shit. I did see her a couple times since that because we have mutual friends. I was friendly with her , but only because I wanted to try and win her back. She is recently engaged now , but she text me yesterday about random useless stuff, so would you text her back? I don’t give a shit about her anymore. I have a girlfriend and i’m happy. I guess if i were to ignore her i would just feel rude. I know i’m going to run into her again.
