Who knows whether she has a penchant for exhibitionism and therefore she's giving it expression as a hobby while cashing on it.

@OP,
Learn to respect other people's private life. The fact that you work under her doesn't give you the automatic right to interfere in her private life.

BTW, the fact that you're telling us that you allowed your girlfriend to pay for your gate fee without any remorse, weakens me. Only those who harbour broke guy's mentality feel happy doing that ( no offence intended).

Someone should please help this guy. He may be suffering from internal bleeding
