Anytime you hear the "I need Space" thing I suggest you look for evidence of an EA. It's often part of the speech you get when the EA is headed to PA. Check computers, phones, email etc. Do it now!
Totally,
I feel compelled to ask... did you read this advice in the Div Busting Book or the Divorce Remedy book?
Neither, b/c it's not there.
You had very limited information from CO, but you made a leaping assumption ( & a worst case scenario too) that his wife must be having an affair, which you stated to him
AND
then you made a suggestion that is generally opposed by DBing, ie to snoop.
Please,
please be more careful of what you suggest and bear in mind the approach this site has, which is based on MWD's work.
