I dumped a girlfriend about two months ago for this reason, after finding several lies (for example, I searched for resumes she had sent, and found three different age of births... why lie your age of birth on a resume?) I figured that there are no way to know what parts are true and what are not, I found no pattern, it is impossible to know when she lies and when she don't.
And after reading about Ms. Shirley, I felt like I was reading about my ex-girlfriend (including stuff in the comments, like people that DO like her, but did not knew she lied so much), I am upset that I cannot believe her anymore. I am upset that I don't know if the good moments were actually good, or acting. If the praises were sincere, or manipulation...
