What did you do after you found the evidence you needed about your husband? I am sure I can find a time it isn't unlocked but what do I do if I find something on it that confirms my suspicions?
Don't do anything right away if you gather info to confirm your suspicions. You will need to formulate a plan.
If you have the urge to confront H, come to the boards to vent. This is a great place for advice and support.
