Oh Jesus!!!

Okay so I had this really close friend, we were like sisters. But she befriended me over her ex. Me and her ex were really close, he was like my brother. She felt as if I was going to steal him from her. I honestly feel like that’s her personal problem because that makes it obvious that she is insecure in that area. Well they ended up breaking up for good and me and the dude was still cool because I’m not about to befriend someone just because you did. Well, long story short. She stopped talking to both me and him. It’s been almost 2 months now, but recently he had hmu saying he wanted to have sex. And I was so surprised. He told me that he been wanted to. Well today I went to his house and we had sex. Am I a bad person?? Me and the girl aren’t friends anymore and they aren’t friends anymore. He said that what we do is gonna be just between us.💁🏾‍♀️ I think it’s okay. Right?🤔
