Input: Some backstory. Last Saturday my girlfriend went out to drink with her friends and ended up at her ex’s house. No big deal, I’ve met him and up until then wasn’t worried about him. Flash forward a few hours and she’s been drinking. I get a FaceTime from her where she’s frantically looking for her contact in his bed. She tells me flat out that she made him leave the room so we could talk. I hang up to process what I just heard. I text her asking why the fuck she’s in his bed and she said that they aren’t doing anything and she’s just trying to sleep. That’s a huge red flag for me. I tell her to get out of his room and to sleep on a couch, which she does, and I tell her goodnight. Flash forward to last night. She texts me to tell me that she’s going to play beer pong at his house with her friends again. I tell her I’m not comfortable with that because we still haven’t gotten through what happened the week before. She tells me that he’s her friend and she wants to see her friends tonight. I tell her that if she wants to go there she can be single because I can’t trust her with him at this point. She tells me she’s going anyways and then we break up. I told her this is a direct result of her actions from the following week and my inability to trust her drinking in his house. So Reddit, am I the asshole here??
