You say there is nothing more she can find out, and yet she "wants to see" what you were seeing. So you have not told her everything. You have not shared your ID and password on AFF or whatever you were on. You have not given her the exact names of the pornography sites you visited.
I'm not saying that you should. I don't think it will really help her in any way. Even if you share everything with her, at this point she has no reason to believe that you aren't holding something back. You are correct that things won't get better if W continues like this forever. Eventually she will get tired of it. It will take some number of months, at least.
You might ask her if she thinks it is healthy for her to spend all this time on the computer, and whether she might find what she is looking for more quickly if she helped you with your IC. (Have you tried talking to her about it the way I suggested above?)
As for divorce filing, she can get a divorce without you ever signing anything. The whole purpose of having the other party "served" with papers is to have a witness (the server) that you recieved the papers--that you were properly notified. '
If you do not respond in any way, your W will recieve a default judgement, giving her whatever she asks for in the complaint, in the minimum amount of time, usually 60 days.
