This girl i'm dating seems to be losing interest in me. I showed up at her house yesterday and she was being a bitch for some reason, instead of being cool and laughing like she usually does. Could it be a PMS thing or could I have pissed her off somehow? Maybe it was because I showed up drunk at her house. Also, she said that whenever she gets drunk she makes "mistakes". What the hell does that mean? Is it a warning to me that she may cheat?
