Dear Annie: I’m 23 years old and had been dating my first girlfriend, “Sara,” also 23, for almost two years before we broke up just a few weeks ago. Over time, I’d noticed several inconsistencies in her stories, which my family also picked up on. For example, she claimed she was punched and knocked down at a store but showed no bruises or injuries, and no one -- the store or law enforcement -- followed up on the incident, which I found odd. Another time, she said she was threatened with a knife at her workplace. Again, no authorities followed up with her.
