ok. I am confused

hi. me Again

This is a new message that the same person from my last post let me today.

Muskuratay raho. Mujhe tumm yaad aatay ho.
 
So, I am confused. What language is it? Is it like local dialect of hindi? I am actually fascinated enough that kind of want to learn at least a bit of it but really don't know where to start.

Thanks guys!!!
