I've just read all your posts. You've gotten great advice from all the good folks here.
Let me say that I think your situation is actually not so far gone as you may FEEL it is. Remember, what's real and what you are feeling may be totally unrelated.
Some general thoughts.
1. Time is on your side. If she has a 2 year plan, then you've got plenty of time. So relax. Exactly where is she going? Sounds like she's stuck. Maybe give yourself a week off and stopr worrying.
2. She's unemployed. She needs to get a job and initiate a move out of the house, therefore, inertia is on your side. Just don't act like a jack ass and she'll stick around.
3. Don't ask her to move out yet. It's always preferable for you to live together for her to see your changes and get curious on your whereabouts.
4. Don't ask her to sleep in a different bed. Let her move to the basement if she wants to.
5. Give her tons of space. That's emotional space, not physical space. That is, don't pursue her. Don't hover. Don't feel like you have to make yourself scarce in your own home if you don't want to. It's your home. Don't let her crazymaking determine your actions.
6. Have fun, get a life. More importanly, find youself. Is there some part of yourself you've lost touch with? Are you passionate about your life in general? Have you found your call to adventure? If you are like me, there probably came a point in your ligfe where you lost your nerve and became boring. Time to man up. Become the warrior you were meant to be. Get your self-esteem up.
7. Going dark is not the best term. Perhaps try "Moving on" for size. That means your life is moving forward with passion and adventure with or without her. You are acting not reacting. At this point, it's OK to include her in the fun if she asks. Put most of your emotional energy into your own life, not your marriage. Save yourself, and maybe your marriage will be saved.
8. Experiment and monitor results. Try drive-by compliments, "Wow, nice ass honey." Offer a back-rub. Drop a rose on her pillow. Throw her off guard. Some of these things may seem like chasing, but they are more to have a little fun and see what happens. You guys don't seem like you are in the desperate stage that requires LRT. If they backfire, then backpeddle and try something else. Hey -- she's not going anywhere for 2 FREAKING YEARS, so you can try anything you want. ;-)
9. Your wife really needs to get a life. She seems to live on that stupid game. YOu can't pull her off the game, but good golly, it seems like an addiction. Oh...by the way, DON't block the game, that would be so desperate and pathetic, that you are practially driving her away.
10. Frank_D on the boards once told me that most people's responses to affairs is: #1) Get out of my house, bitch. or #2) Please, please, please don't leave me, I NEED you so much. Niether of these work. DB-ing is about: working on yourself, having fun, being creative, giving her space and see what happens.
