Is it normal to have sex with my ex girlfriend's best friend?
My ex girlfriend and I have been broken up for about 4 years now. I broke up with her because I found out that she was cheating on me with one of my close male friends. Her best friend, who is a female, told me last year that she always found me sexually attractive and ever since then we been secretly having sex and me and her best friend's friendship is unaffected by the sex. And we even hang out with my ex girlfriend regularly.
