my wife requests space, deattached from me

[WillDo]

Our relationship has improved but there is still the OM.
I snooped a bit and realized things still going on secrecy.
I am having trouble on how to stand on these. I am keeping
all her actions deep down to save the marriage. Many of the
MidCrisis articles talk about how to beat these. And as Michelle
says if I draw the line, the odds are she will be defensive again.
Haven't done that for a year. I had been refraining from snooping.
Couldnt resist this time. Probably not here for advice but someone to talk to.
I had spoken a year ago to a friend but stopped after the books articles I have read. How long more? My patience is there still.
