<human>: So last night my girlfriend went out to a club with her friend. She told me she would be sleeping at her friends. The next day she tells me she did indeed end up sleeping at her friends house. Then I creeped on her Facebook (I'm terrible, I'm sorry) and found out she actually did not sleep at her friends.

I confronted her and she broke down in tears telling me she got way too drunk, got separated from her friend and ended up stumbling around the parking lot throwing up. She said a guy came up to her and asked if she was ok and that he then gave her a ride to his place where she slept on his couch.

She swears nothing happened and that she lied because she thought I would be mad that she put herself in that situation. I want to believe her but part of me is scared she cheated.

Summarize the given text in a few sentences.
<bot>: girlfriend got drunk and slept at another mans apartment, she swears she didn't cheat. Not sure if I am being naive by believing her.
