First of all, she gave her password to your friend shows her level of dumbness. She doesnot deserve your friend lol

Secondly, the guys was not supposed to go after her private mails. Coz  tyati pahiely dekhi ko crush rahechaso, but still past ignore garna sakena.

girls ko kaami chiana, if he can move on , forget abt that girl . But if he still wants to settle down with her if the details are reasonable, then it would be better to contact THAT GUY ( her ex) . What was the reason for their break up ? Worst reason would be she left that guy coz your friend won DV which he will never get to hear from her side.   If there were other things, then it depends on your fren and her.  How deep was their relationships, Is the girl mentally prepare to forget that guy ( overcome her feelings over that guy) etc.  

About the second guy, it could be just contract marriage as it was supposed to be secret marriage. Your friends need detail info on that.

The best he can do is :
Apologise with the girl for reading her emails. 
Then he is ready to ask whatever he wants to ask
What was the relationship with the first guy( married guy) .
How long did the relationship lasted
How deep is the realtionship ( could be online only , could be best friend or .....)
Why that guy married othe girl ( if posible ask this question to that guy too if he cooperates)
Would it be possible for her to forget about that guy , particulary the relationships with that guy?

Who is second guy,
Is he a boyfren too?
What happen to the plan of getting married with that guy?

and othe things your friend thinks he should know.


Take a time and let your friend decide after he knows all of these clearly.
If your friend wants to be with her, dont go for court marriage only. Make sure everyone especially her families and friends know about the marriage.
I dont know if it is possible. If it is , dont file for her residency here until you guyz have kids together. and let her know abou this before marriage coz I have read couple of times in sajha that the marriage lasted until the girl recieved GC.




If he wants to leave her, they are in different states. So he can just ignore her phone calls, emails, texts and go with different girl or he can write one email to her  and stop whatever is going on any time.
