My daughter's dad is being really creepy. What should I do?

So the weirdest thing just happened to me. I have been broken up with my daughter's dad for about a month now.

Yesterday he texted me asking for a favor. Then that was our conversation!!

I refused to text him back and he finally called me and I kept saying he is so gross for asking that of me and making me feel like a sex object. He started getting all sad saying "well if we aren't together, I'd like to still be able to fantasize about you and enjoy you"

Who does that?!
