bidaha ki sefere unutma emi

this is by a native speaker so i believe there are some spelling mistakes... help!!

don´t forget the next time, ok?

thank you, but..

 what is EMI?? never heard of it

"E mi?" is an exclamation question in spoken language. It means "Tamam mı?" as question for approvement / to be sure that the person heard and/or understand your words before this.

For example, my grandmother tells me when I am leaving her house to go home:

- Eve gidince beni ara, e mi? (Call me when you arrive home, ok?)

Which is because she wants to be sure that I will call her and I will not forget to inform her that I arrived home well.
