If you treat every relationship like a crime scene, don’t be surprised when nobody wants to stay.

After you have been burned, suspicion feels like the only sensible setting, and for a while it probably was. The trouble is that constant investigating changes what it is like to be near you. People who have done nothing end up defending themselves, and eventually they stop trying to pass a test with no pass mark on it. The caution that once protected you starts costing you the good ones.

None of this means deciding to trust everybody by tomorrow. Pick one person with a clean record and give them one thing without checking on it. See what happens, and let the evidence build at whatever pace it needs.
