TLDR: Girl is inebriated and I'm realizing shes crazy.

Arranged a FWB thing with a girl a few months ago. Everything was great from the conversations to sex. I get back into town for the weekend after talking to her and decide to stay the night.

First hour: perfectly normal girl as I had previously met

Second Hour: Clothes start coming off and she starts being very scatter brained and all over the place

Third Hour: mood killed and I'm generally concerned about her as she isn't forming complete sentences and trying to convey things with very loosely fitted analogies, to what I don't know

I asked if she had allergies? no. if she took anything? no. If she drank anything? just the two sips from a bottle she opened in front of me.

She passes out.

I put shorts on her and cover her up.

Immediately go to her roommate after dressing myself and ask if she has been weird lately or has allergies or took any drugs. I sent the roommate back in to sleep in the room after I explained everything that happened and illustrated we did not have sex.

With the roommate we smell drinks in the room and she has a cup of tequila and god knows what else. I say I'm going to sleep in the living room.
