I just got out of a relationship and the last 3 months were pure hell. My ex is still very obviously in love with me. He's trying to get his life together for me, but I don't trust him. He's a habitual white liar. I recently started hanging out with someone I dated for almost 2 years. He's been my best friend since I met him and we have been pretty much inseparable for 4 and a half years now. Neither of us want anything serious, but we don't want the other person messing around on us. We didn't previously have sex, but we did everything close to sex lol. I'm torn about having sex with him now. I want to, but don't want to be "that girl". I'm not sure if he can keep quiet about it, and I'm scared I'll get too attached to him if we do. I also don't want my ex to find out if we were to ever work things out. I also feel odd bc my ex had 3 total sex partners and I've had 7. I'm not sure what to do. My body says yes, my head tell me to think about it more. Help!
