f, my boyfriend abandoned me after clearing an exam in the most horrible way just ghosted me without any explanation. He gave me hopes to marry , called my mom and what not and now is going out clubbing and partied with his new 1 week old friends. He said you have “30 secs to talk” I am over him but it’s sad that I am living with trauma while he is enjoying.
