So long story short, I ended up having sex with a guy that one of my close friends is friends with. It actually happened to be my virginity. The guy is actually a really crappy person as far as women go, but that's another story. After I found about about his new sexcapades exactly a week later, I tried to have a conversation with him to tell him that what happened between us wouldn't happen again and that I wasn't mad about him and this new girl (we weren't together and neither of us wanted to be). He completely ignored my attempt to meet up and talk face to face so I ended up texting him, which he also ignored. I found that to be completely disrespectful. Our mutual friend (who I am really close to) still remained close to him even though he literally took my virginity and left, which I felt was strange. Then recently she tells me that the guy had been talking about me to her and other people rudely and saying a bunch of things that weren't true. He even took a screenshot of the text I sent him and put it in a group chat for other people to see. This obviously makes me feel even further disrespected. Loyalty is a really big thing for me when it comes to my friends. My friend (who still is friends with/talks to the guy) seems to think that she is being loyal and a good friend by still associating with someone who would disrespect and talk about me the way he did. She also defended him every time the situation came up in conversation between us and she wasn't the for me at all when I was going through the initial attachment pain/emotional breakdown (thanks to that amazing oxytocin! I've definitely learned sex is no joke ladies). Am I wrong for thinking she is disloyal?
