Can someone help me understand?

Ok so my ex has been acting shady. One example is he texted me just until I was back on his bsf list (he has a girlfriend of almost 3 months) and whenever I talk to my guy friend (his Best friend) and talk to him (my guy friend) about my ex he acts weird and shady. But the other day my ex texted me "so I heard you still like me 😔" like what does that mean... like the emoji? Is he hurt like I don't understand...
(Keep in mind my ex broke up with me)
