my W doesn't regret her affair

[GH31]

Given that we are separated, it may be difficult for me to completely verify it, so at some point, I'll have to trust her.

Here's the deal Future. You won't be able to trust your wife until she starts being trustworthy. Once she's been trustworthy for a period of time the trust will return.

If your wife wants to win your trust back, no-contact will be easy to verify because your wife will invite you to hold her accountable. If she baulks or makes excuses about participating in accountability measures, you know she's leaving wiggle room for contact with OM and it really isn't worth going down the piecing path with ongoing contact.
