First let me say that if are a month in and have not and are not persuing, bravo to you, you are ahead of the game IMHO. I am 5 months post separation in and am just 5 days in non-pursuit/LRT mode. Read my ridiculousness if you wish to see why it is best to totally leave her alone and not worry about what she is doing, because interefering in any way will in all certainty make things worse...
As everyone above said, GAL, work on yourself, make happiness without her, and leave her be. I know it is hard but that really is the only way, or at least I hope it is, because I have tried everything else under the sun in the last 5 months and am still in the same spot if not worse than I was before.
I am not going to lie to you, it is going to be tough, as I said I'm physically separated for 5 months and am still going crazy, so I am right there with you.
Keep your chin up, and know there is support here when you need it. I will be praying for you, your wife, your marriage and sitch in total in the meantime. :-)
