Am deeply broken, please someone help me?

It might sound weak but it has been 19 days since i broke off with my boyfriend, n he moved on immediately with another girl. Looking back the way he was treating me it all makes sense that he was pushing me to flip n say the word. Im trying so hard not to stalk his social media but its so hard. He is narcissistic n i feel kinda of bad to the new girl because in the end she will end up like me. Ik leaving was the right decision but i feel so hurt n why do i want him back, whyy? Im so hurt n i can't take it anymore. Please anyone help me with anything so this pain goes away please
