Need some advice from you seasoned vets considering i’ve been in this LTR as long as some of you have been with yours.

Back story. My GF and her friends are all staying at an AirBnB for a week, to hang out and party. Its 6 of us with me being the only guy. We arrived on Monday and its been pretty much daytime outdoor activites and drinking at night every night. I’ve known most of them for the past 10 years and have a pretty good rapport/relationship with all of them.

Fast forward to last night. The plans were to do some site seeing and then hit the bar at night. As the girls were getting ready for the night, i began pregaming. At the point of leaving the house, i was already pretty buzzed. As the night goes, we’re all enjoying ourselves, and i continued drinking. By the time we reach home i’m pretty hammered. To the point that i occasionally use the wall as a brace not to fall as im walking. From what i can remember, a few of us remained on the couch watching tv and just chatting. I recall my GF bringing pillows for her friend, (lets call her Jane) so that Jane can just crash in the couch she was in. I jokingly asked for one too because i couldn’t make it upstairs. My GF laughed and told me i better crawl my way up. At this point i’m assuming is when i blacked out because next thing i know i woke up to everyone gone and Jane knocked out snoring, with the TV still going. I got up and made it upstairs. The way the rooms are setup upstairs, they are all pretty much side by side and the bathroom on the opposite side. I enter what i thought was the room my GF and i were staying in, and laid down in the bed. I placed my arm over her to cuddle and laid there for a while. I was semi erect and she slightly wiggled her ass into me. At this point i started fondling her breast and proceeded to pull her shorts down and touch her. About a min later she turns around and tells me to leave. Thats when i realized i was in the wrong room & i was in Alice’s bed. I said sorry and left immediately.

Morning comes and i’m in the correct bed. My GF walks me up hysterical, asking me wtf did i do to Alice last night. Telling me Alice is on the floor crying that i came into her room and took her pants off and touched her pussy. At first i didnt recall the event but I reminded my GF how hammered i was and explained that i walked into the wrong room and thought i was laying down next to her (in the dark they do resemble each other, being the same height, body build and hair style). My GF then tells me Alice wants me to leave as she doesn’t feel comfortable with me around. I tried to plead my GF to let me apologize to Alice as I would never do anything to violate her. It was seriously a drunken confusion. I have never made any advances or any moves of such on any of her friends before. My GF broke down crying, and after feeling so guilty & ashamed of myself. So did I. I agreed to leave the house but now I still feel horrible for what happened. If Alice never woke up and asked me to leave. Who knows what would have happened.

TL:DR i got hammered and ended up in my GF friend’s bed. I groped her and she told my GF the next morning. Now im being looked at as a predator.
