Rephrasing
She was with a guy who used to be her friend before her marriage and she wanted to get a picture of them together from her.

But some questions do come in my mind
Why the did she have to go to him to get the picture. She could have asked him to destroy the picture. Why did she have to go to a desert to get the picture. Why did they have to be in the car together when they could have met in a public place, like mac donald etc.

I do have some more questions but I dont want to start a debate at this stage against myself.
