Facebook stalker its annoying?

so apparently i have a facebook stalker and i think its bc this girl is jealous that i have a bf. basically things got out of hand with 1 of them. She flew out to SF the following weekend to prove she is better than me (or not sure what she's trying to prove) or that she makes more money than me. Well tell me if this makes sense. Why does she only check in on facebook at BART & the Beerfest and at a Sushi Bar but no pictures proving she was actually at these places? the only photos she uploaded on facebook were pictures of herself were standing in front of a mall, on the ferry and standing on a street corner with friends throwing up a peace sign. mind you she didnt check in at any airpoorts to and from SF so too many loop holes if you ask me especially if she is trying to say she was ACTUALLY there bc i still think that's bullshit. Another piece of information she took pictures with some guys and she tagged them why does 1 of them say he lives in LA (confirmed online-google) and the other says he lives in SF according to him on FB. could she have used her LA friends to pose as SF random boys to prove she was really out there? The whole thing doesntt add up let me know what you think.
