I watched thos years ago randomly on late night TV wheb I couldn't sleep!
I'm sure it was Turkish..
So a young girl gets married in a village seemingly to a handsome young man, but as she gets taken to the inlaws town after the wedding it becomes apparent that she has actually been married to the father of the young man as his wife is dying and it was her who arranged iy. Yhe young man is gay also so it was convenient to pretend she was married yo him.
The other siblings in the house resent the young girl and she feels alone, she eventually starts an affair with a boy her age who works in the supermarket but gets caught.
I think she ends up having a baby towards the end but can't remember.
I've Googled and nothing that comes up is the right movie.
