I think this song is about being betrayed by someone or something you KNEW was true.

You are never the same after that.

"I can't believe in anything I know that Mary lied" is the reluctance to trust anything afterwards.

The you gotta come over to me part is about how she will not put herself out there for people who will stab her in the back. They have to come to her if they want something from her (friendship).
