A few weeks ago I (21) was bored and i was hanging out with a good guy friend (22) of mine. We have been friends since high school and we have never gone out. We have always been a bit flirty. Anyway, I told him I was bored and came onto him. We spent the weekend having some great sex. On Monday morning he confessed that he has like me for ages. I told him I wasn’t interested and I was sorry if I gave him mixed messages. He has since called me a slut and now his sister who was one of my best friends has stopped talking to me. Am I the asshole?
