Why can't I love myself?

For all whose seen my recent post from last week. I finally walked away from the situation, but for some reason I can't stop my mind from thinking about that asswh*le. Ever since I ignored him his stopped viewing my Instagram stories all together, I can't understand why this is bothering me. He treated me like a whore and I still look on his social media and I'm mad as hell that his got my replacements. Wtf is wrong with me, his a dick. How do I stop feeling this way about someone who doesn't give a f*ck?
