Ok, to make a long story short. My friend is a fucking whore if I tell her (which i have) she takes it as I'm joking but I'm not. Friday night she fucked a dude, came back to my place when I left her at the bar she was broke so how the fuck did she come back with 200 dollars? After talking for a bit we went back to the bar and she found another bed buddy and fucked that guy too. Saturday morning I walked over to her house, completely different guy in her bed.

This has been going on for a while, but how the hell do I tell her so she knows I'm serious? Any help? I'd apperciate it.
