broke up with him

I broke up with my bf bc we weren't good for eachothers mental health, he's now talking shit Abt me to everyone and not telling them the full story Abt us breaking up, he says I'm being over dramatic even though we've had 17 arguments in a month and I'm tired of fighting with him but he won't stop being an asshole and acting like he's superior than me, I don't even feel sad that we broke up I just feel relieved that I don't have to deal with him anymore
