I also don't like being in this home anymore or the arrangements. My W is being rewarded for her actions I.e. the house and standard of living have not changed and she has absolute freedom to do what she pleases.
Read this again and then explain it. What actions is she being rewarded for? What is the reward?
Your W is going to do whatever she needs/wants to do. You have no control over that. The sooner you can accept that and start to work on you the better you will be. It does not come easily. You have to work on it but working on you is a much better use of your time than snooping to find an affair.
Would an affair be a deal-breaker for you? Or would is be another way to fuel your anger and keep from working on you.
So what are her other complaints about you? There must be more than getting the kids to school and laundry and domestic chores.(you're 2 busy professional with young children. have you ever thought of paying someone do those chores? a housekeeper is much cheaper than a D)
Tell us what you know you need to change. Read other threads, post to them.
Work on you, the only person yo can fix.

Let me give up the need to know why things happen as they do. I will never know and constant wondering is constant suffering. Caroline Myss
