Friend pretending to be a Army veteran..?

[Luke]

Your right its disrespectful, one of these days u wont be the only one to find out and her 15 minutes of fame will be up.

[Jess]

Of course you should. Then you should distance yourself from her. She sounds like she has severe mental issues or is just a pathological liar. Either way, why would you want to deal with her drama? If you do decide to confront her, be prepared for an argument because she likely will try to defend what she is doing. And that alone should make you realize she is not worth having as a friend.
