Walk away Wife having affair

[Hurt06]

Married 13 years with three kids 6,8, and 12yo girl. Wife had asked for a separation. I had to attend training and agreed to stay away to let her think about what she wanted. While gone I discovered that she was having an affair. I suspected this all long but she was masterful in lying and deception and it had been going on for months before this. Mostly they have been communicating through Viber and Skype as these can be erased and hidden more easily. After confronting her she denied but I had already complied the evidence and she eventually admitted what was going on insisting that it had not gotten to sex yet. To top it off the man she is seeing is a divorce attorney! She continues to lie, manipulate, and hide many things and I honestly don't know when she's telling the truth about anything. I have asked her to break off her relationship to see if we can salvage our marriage but she says she has stopped talking to him for the moment but still wants me to move out and leave the house. I think she has only hidden her communications deeper. I have found love words to the other man. Any advice or insight in how to stop and fix this would be appreciated. I can forgive her and want to save our marriage and will make any changes necessary and have already changed my life radically.

PLEASE HELP!
