Long distance relationship?

So I'm in a LDR. We've been chatting for about 2 months, and decided to start a relationship last week.
Just a few hours ago, she says she wants to go out with this guy that she's supposedly only been friends with (for over a year).
She claims nothing has happened between them in the past except for a little bit of flirting.
She also neglected to tell him that I'm her boyfriend.
She agreed not to go, but since she's over 1000 miles away. I don't know if I can trust her.
