All women are whores

I need to get this off my chest. I had to use a throwaway because she knows my reddit account.

A few months ago, I finally made the choice to ask a female friend of mine out. She had made several 'nice guy' comments, which gave me the courage. It worked. She said yes, and we started seeing each other romantically. She said, because we were friends that she didn't want to rush it, and we didn't have sex, she also knows I'm a virgin. This is all going fine when a week ago, while we were watching a movie she started crying. When I asked her what was going on, she just kept saying she was sorry. After ages of this, she finally says that she had slept with some one a month or so into us seeing each other, and that she couldn't keep it a secret because I'm such a nice guy, and she feels she's "not nice enough for me." After pushing her for details, she says 'they' instead of 'he' when explaining what happened. I start freaking out and demanding she tell me exactly what happened. She then tells me that she had a threeway with these two Nigerian guys one night after she went "out with the girls." I told her to fuck off, and that I never wanted to see her again. I don't want to see any fucking women ever again. They are all evil.
