Guilty

Reality: He messes around with other girls, and totally fucks over my heart. Asking me to pick him up from a girls house he had got caught at. When him and I have been friends for years, that started having sex(I feel played). I draw the line when he fucks me, and asks me to pick him up from a girls HOUSE. So we are no longer talkin. He says he doesn't care because he thinks I'm talkin to this other guy K. Which I wasn't.... K was coming on to me, for awhile now. I turned him down every single time, because I liked the guy I was already talking to(lost my v card to him). But the very next day, after I got into a argument with him(t). I had gotten high, and started flirting with K. And he knew I was flirting, basically begging for the dick. He gave it to me and put it down. Dude I feel guilty, I did exactly what T thought i was doing. But should I feel bad, if he was running around with a girl? We weren't together, which is what he would usually tell me. I mostly did it for attention, and felt sick after it happened. I'm not that type of person. Let me know how you guys feel about this...
