If she is realised that she messed up BIG TIME from her deepest consious then she deserves a second chance...........I would if I were her husband....Pehli galti to Allah bhi maaf karta hai, hum log to phir bhi insan hai !!..........Subeh ka Bhula sham ko ghar aye to sab kuch thil hai.........der raat bhi ghar aye toh bhi thik he hai ...: )
She committed zina , most men in our culture can never forgive and forget it, if she was talking to someone or was just going out with another man then gorgiveness may be possible.
In these kind of situations the best judge are those who are living it, these things cannot be decided based on assumptions.
