need advice and understanding

So here's my story, I apologize for being vague on the locations. Until October of last year I was diagnosed and being treated for depression. In September the doctor started weening me off the drugs and by the end of October I was feeling like myself again. Last November, the 11th to be exact, my wife informed me she wanted a separation. She told me that she would stay until christmas, but then she was gone. I was told ILYBINILWU. I pleaded with her to reconsider. she said her mind was made up, she needed time to think. After that she went to her parents house, "to think." I was unable at the time to give her the space she needed, I pretty much made every mistake that you can make. This ended up driving her further away from me. When she came back I was informed that she was moving in with her parents, which is out of state. I was crushed. The problem is that she travels for her job, and I was not comfortable with her parents "raising" my kids. Not that I don't think they are/would make wonderful parents, but it's not their job to raise my kids. So I left my home state and followed her. Before she left she told me that she wanted January to think about things, and find herself. I agreed and I have not initiated contact with her since she left. This is where things get confusing for me. We have talked almost every night. When she calls to talk to the kids, she always asks to talk with me. Never about anything serious, but she wants to talk to me. When she's home on the weekends, she invites me out to spend time with her and the kids. I was even invited to an upcoming concert by my 16 year old daughter, only to find out it was my wife's idea. Well today I did something I'm not proud of, I went through her email. The issue is I found out that she's been having an emotional affair since at least November 10, possibly longer. I also found a receipt for lingerie and a plane ticket from a location not ours to the location where she is working. I'm sure that this week the affair turned from emotional to physical. So now I don't know what to do. I still love this woman, in spite of this affair. I need to confront her when she comes home on Friday, but I don't know what to say other than to ask her to stop the affair. I'm finding out that pretty much everything she has told me and her family is a lie. Everything she's done over the last 3 months is textbook midlife crisis. In the last 3 weeks I have become really close with her parents. for a long time I thought they didn't approve of me. I have found out recently that isn't true, just my own neurosis. The problem here is that they are the only ones I have to talk to. They are my support system right now. My family is worthless when it comes to anything more serious than the latest family drama. And I have destroyed every friendship I've had over the last couple of years because of the depression. Needless to say, her parents know about the affair, but they are the only ones, and I had no one else to talk to. I love her so much and I have made great strides in moving past this separation. i was finally able to distance myself from the situation and work on me. However, today I took a few steps back. I just don't know what to do at this point. I'd really like some objective third party advice and understanding here.
