I'm 20F, and I've been active on dating sites ever since I was 19, it's been a year and a half. I've been on multiple dates, a few of which have ended in night stands, and casual sex.

A couple of nights ago, I was about to meet a guy(23M) I met on bumble, and stay over at his place. I have been physical with him for almost a year now. I told about this to my bestfriend(20F). She's been my bestfriend since we were 12 years old, and she is the closest person to me on this planet. She was upset that I'd be meeting him. She was never like this before. She used to ask for details about the guy, ask me to be safe, and say "enjoy" and all that, but this time she was not happy.

I had taken a resolution a few months ago that I wouldn't sleep with someone unless I'm committed, she brought that up. And to be honest, that was a fair argument. I was breaking my resolution, and I told her "I know I'm in the wrong, but sometimes I have these urges I cannot control". I've broken that resolution before as well, but she hadn't responded to those incidents with the unhappy tone.

Apparantly, one of our mutual friends (23M) had spoken to her about me asking if I've ever taken a right decision when it comes to dating, and my bestfriend defended me while arguing with him saying "it's her choice". But later she pondered over it and realised, she never scolded me for being wrong, she said she's always said to me exactly what I felt and validated those feelings all the time. She thought though we were bestfriends, we were too formal with one another. And I had asked her, not to do that, and be honest with me. I asked her to tell me on my face if I'm doing something wrong. She said "okay, go enjoy this one night, we'll talk later"

That night though, things ended in a threesome, when my date asked if his friend could join. I was familiar with that friend, as he was my date's roommate, and I had met him a few times. I thought it would be a cool experience and said yes. I told this to my bestfriend, and now she is upset that I don't value her words. I'm trying to convince her that what happened that night was purely my urges taking over. But that doesn't mean I don't value her, and her opinions.

She's mad at me, and is not talking to me. She's not responding to my text messages either. How do I fix it??
