Ripken - Trying LRT and going dark. Now what?

Ok. So here's the full situation. She filed for divorce Saturday out of the blew. She had been saving up since January but never did anything. She lied to me about the affair and then told me today she wanted a divorce and filed. I asked her repeatedly about the affair. She asked why it was important, never admitting it. I told her because I'm not an idiot and deserve more respect than that. I felt I was owed at least that much to stop lying. She said fine and that they have been physical for a couple months including Sunday night. I asked if she loved him and she said she didn't know but knew she didn't love me and it was no longer fair to me. Agreed to mediate and do no fault divorce and 50/50 shared custody with the boys. Also said she wants to stay in the house until we sell it and then we both move on to new places. I told her that I can't control if she wants a divorce and that's not what I want. I also told her I don't want a fight and want to divorce well. However not sure what to do from here. 21 days from yesterday for me to respond and then I think 2 months until finalized. She made the decision to divorce and still wants to be with him. What's next? What can I do? Besides lawyer talk advice
