Another way you can push your spouse away is by tracking what they are doing. It sounds obvious, but don’t put a GPS tracker on their car, and don’t try to monitor their emails, texts, or social media. When they find out (and they will), it will infuriate them and push them further away.
You may even feel like you want to hire a private detective to really find out what they are doing, but ask yourself how that will serve you rebuilding your relationship.
(Remember, NO snooping!)
