Sorry to be blunt here.If she "pretended" to cheat on you.How are you sure it was just pretend? Maybe since you caught her she is trying not to lose you.My exwife thought i was cheating on her so she cheated.The day i busted her she was VERY shocked when i told her i NEVER cheated once.Word to the wise proceed with caution do not waste 11yrs on a skippy like i did.
