Adultry

My wife recently went to Bangalore stating she has an office training and was later discovered missing from her hotel room at night. I informed the same to her office and learned that there was no training being conducted and her bookings were not made by the company but was a self booking. Incidentally there were some 30 other employees from her company who were staying there that night and they had company booking. Upon inquiring eventually she had to admit that she was not in her room the night before she was due to attend the fake training and came back home the same day. She has admitted to sleeping with somebody but is also denying having any relationship with anybody. The other side of it being that someone influential with deep pockets within the company is using her and she is not willing to disclose the name under pressure. I am currently unemployed and we have a 12 year old son. Under the current circumstances, what are my options? Is there a legal way to make her speak out so that I can press 497 o the concerned person.
