You’ve asked for my opinion, so I am going to give you an honest answer.
Trust your instincts, and listen to that little voice inside your head.
While there is an outside chance that she’s telling you the truth, as you’ve described the situation to me (especially the change in behavior) the explanation does not ring true to me either. That, or perhaps she’s bi-sexual? I’m just throwing that possibility out there, because there are more women than you may think experimenting these days…
Having said all of that, here are the telltale signs that someone is telling you is a lie:
* Information Overload: You ask a simple question and get a complex, long, drawn out, (too) detailed explanation, with way more information than necessary. Liars try to convince by revealing too much information and too many “facts,” rather than conveying a simple answer to a question.
* Informational inconsistencies or lack of logic to statements, the stories seem too dramatic or unrealistic.
* Physical discomfort — blushing, sweating, leg jiggling, scratching a maddening itch.
* Inappropriate body movement — unexplained smirks, inadvertent shrugs, lack of eye contact or shifty eyes, and inappropriate smiles.
* Changes in speech patterns — hesitations, odd phrases, slips of the tongue, or quickened speech.
* Repetition: Repeating questions can be sign of someone buying time to formulate her or his lie.
* A strong feeling that something is not right. If your gut tells you that “something’s up” with what someone is telling you, pay close attention to their behavioral patterns (how a person sits, gestures, looks at you, responds, talks, etc.), listen for inconsistencies in information and watch for too much information — someone who is trying to convince you with too many facts, rather than convey.
