Okay so let me start from the beginning. I hung out with this guy who my best friend slept with a while back. In high school. He’s 20 and I’m 18 almost 19. Well he was looking for someone to talk to and so was I. We both said we didn’t want sex but I pull up to his house. He gets in my car. We talked for a good long while. He asked if he could kiss me. One thing leads to another with his hands around my neck and shit and He pulled me on top of him. (I did agree btw) Shit gets heavy and then we started to fuck. Now she slept with him about 2yrs ago and is in a long term relationship now. I’m just not sure if this makes me a terrible person or not. I’m also afraid to tell her bc what if she gets pissed at me. I don’t think she’d get mad I’m just worried she will. Idk any advice?
