Well, even though my wife and I are friendly toward eachother, she still is not moving back in.

At least we are friendly, no more fighting. I am not sure of her motives, but it seems to me she is "testing" me to see if I can remain cordial and friendly while she gets some space from me.
Either that or she really is completely done with our marriage... Either way, all I can do is change MY behavior to be more friendly and hope for the best.
I can't control her decisions.

I am just going to focus on me right now, and channel all my energy into music and work. . Me-time.
