If you look at my post history you will see I took a girl to a concert for a second date. It went really well and there was a lot of good vibes there. It felt romantic. Anyway, we went to a club together after with some of her friends and I ended up talking to the one towards the end of the night and despite the fact she had a boyfriend, she was really into me. Me and her went back to hers and I fucked her. She kept telling me ‘don’t mention this to x’. However I bumped into the girl I went on a date with her and every time I saw her she wouldn’t even look at me (I didn’t try to speak to her or anything) I knew something was up. One of her friends said that I really hurt her feelings so obviously she found out about the situation with me and her friend. Part of me thinks I fucked up but the other part thinks that maybe this will increase her attraction for me in a weird way, because girls like men that have abundance. How should I go about speaking to the girl? I’m going to leave it a bit then probably send her a text. How do I salvage this situation?

TLDR Went on a date with a girl and ended up sleeping with her friend. Girl I went on a date with found out and is now giving me the cold shoulder. I haven’t spoke to her since the night but found out through one of her male friends that she found out. How do I go about fixing this mess?
