I feel sad for my ex, should I talk to him?

Summary: my ex was treating me very bad, he insulted me, my family, my religion. He knew i would never leave him so he did whatever he wanted n didn't care how i felt. I was with him through it all for almost 3 years. It was hard for me to leave but i finally did it because of how he was treating me despite all the efforts i did for him.

But he contacted me yesterday wanting me back but I said no. So he deleted his socials n all that n i feel like he might be going through something. I dedicated myself to him for almost 3 years and i kinda feel bad that he might be going through something n alone because he has no family.
