Broke up with my scorpio ex - he texted me later

Me and my scorpio ex broke up, it was a very intense serious relationship however not long in duration.
We used to have multiple fights, maybe because of incompatibility, toxicity etc
I broke up with him, and he agreed to it, over a very big fight.
I still wanted a last goodbye but he said he won’t be able to breakup if he looks at me because he still loves me

The next day he texted me “I hope you’re doing okay” I didn’t respond to it because he had cut the last call on my face

Im confused about this behaviour. We are in no contact now. He still reposts reels about me, the breakup, about him being heartbroken, having no will to live etc on his social media account.
