I will probably not be the only one to tell you this, but it is VERY unusual for one spouse to ask the other to leave, or for one spouse to leave, because they "need space" if there is no infidelity. Does it happen? Yes, but VERY rarely.
Do you know what an "emotional affair" (EA) is? If not see
Emotional infidelity - my wife had a couple of EA's before her physical affair, and I thought they were "just good friends" - which was true, but I did not understand how their relationships were hurting our marriage and a sign of what was wrong with our marriage.
Now, if your W is not in an affair, emotional or physical, she is in withdrawal, and since an affair causes withdrawal, the treatment for withdrawal by itself is pretty similar to the treatment for an affair. Click on the link in my signature line (below) for how to recover from an affair. With the exception of the affair-specific book recommendations, everything should apply to you. The Plan A/PLan B link suggests that Plans A & B are a strategies for seperating a spouse from a lover, but the same strategy is used to bring a spouse out of withdrawal.
IF your spouse is not having an A, I would substitute "Fall in Love, Stay in Love" for "Surviving an Affair" or any other affair book. When you read it (preferably with your wife), make sure you do the questionnaires. Reading it is only 1/10th the value of reading it and doing the questionnaires.
And - oh yeah - why did you move out? Did you WANT to move out? Were you abusive? Why didn't she move out? Do you have kids? In most circumstances, moving out makes reconciliation harder, not easier, so you should probably consider moving back in, though i would need to know more details to be sure.
