Are there any women on Voat? Get the feeling there might not be, but here goes.
So this story concerns two women, let's call them Jane and Kate. I met both of these women on a course I'm studying for this year, and pretty quickly found Kate attractive. I had talked to Kate for a few hours each on a few occasions (usually over drinks at social occasions) and the conversation has always been really enjoyable, but she mentioned her "friend" several times so I figured the lucky guy is her boyfriend and left it at that.
Around December time, I'm meeting some friends for some drinks and then a group walks in, amongst them Jane and Kate. This was the first time I had really spoken to Jane properly, and essentially I didn't find her repulsive nor attractive. That night I get incredibly hammered (to the point where I didn't know where I was), and Jane takes me to her room and we get intimate. I start sobering up in the middle of it and just decide to carry on what had started. Afterwards Jane and I agree that it didn't mean anything and it was just casual. Regretted it slightly at the time, but since I can't undo it I just got on with my life.
About a month ago I essentially get a booty text from Jane which wasn't subtle in the slightest, I didn't particularly want to go ahead with it, but in the end did because I thought my friends would think less of me if I didn't. I go over, and afterwards feel instant regret especially because I went in knowing what would happen that time. I also don't particularly like Jane from this point on because we hold different values and so on.
A few days ago, I'm walking home from classes and I bump into both Jane and Kate (they have been hanging out more recently than they used to) outside the pub and they invite me to join them for a drink whilst Kate waits from her "friend" (same one as before). Anyway all four of us end up drinking all evening, and it becomes clear that Kate's "friend" is actually just her friend, and not her boyfriend, and Jane was again not being very subtle but Kate and her friend don't seem to notice since Jane got too drunk. I turned down Jane's advances several times that night, and I'm glad about that (though I think she's upset with me now).
TL;DR Slept with a girl's friend before discovering that the girl in question is actually single and I have the hots for her.
What do I do? Have I brought this all on myself? Am I a terrible person? What should I have done differently?
