I went on a double date with my ex and her friend and her friends husband. I paid for dinner, drinks and a comedy show because I was going out of my way to try to make an effort to get to know her friends. When we got back from the comedy show we start smoking some weed, and my ex grabs me a beer. Halfway through drinking the beer I can't keep my head up I'm so tired. My body just wants to lay down and nothing more. I smoke weed daily, and this wasn't the same kind of feeling of smoking too much while drinking. My ex suggests "you should go lay down on the couch," so I did. I was laying on the couch my eyes shut, but wide awake. It was hard to move my body, and keep my eyes open, but my mind was incredibly alert.

About a half hour goes by and I hear everyone go upstairs to t he bedrooms while I'm on the couch. I assumed my Ex would come check on me or something, but alas she did not. Upstairs there were 3 bedrooms and 1 bathroom (the only bathroom in the house) and 2 of the rooms were my ex's kids rooms with little twin beds. I notice the light on in the master bedroom and someone is in the bathroom. I look in the kids room and no one is in there. I really had to pee so I'm propped up against the wall just waiting for whoever is in the bathroom to come out while I'm reluctantly looking for my gf at the time. Her friend walks out of the bathroom after throwing up, and I go "Hey have you seen Chrissie (my ex)?"... she completely ignores me and B lines it to the master bedroom and quickly closes the door behind her. I go to the bathroom quick and come out... and then take another look into the kids rooms and sure enough my ex is pretending she was asleep there the whole time. Turns out they slipped me a xanex and tried to have a 3 some while I was passed out on the couch.... I've had some crazy trust issues ever since.

TL/DR: GF drugged me so she could have a 3 some with her friend and her friends husband but I caught them before anything could happen.
