I was at a program with some loser guys(I went back to school for a chane of a career), they were much younger than me (10 years) but still bugged me like hell. After I rejected them, they claimed they all slept with me many times. After the program, my nightmare is still not over. Some of these guys knew some loser guys in my current investment bank. And so These loser colleagues (very young guys) circulate the rumors inside the firm to give me hard time. When finally the rumors quiet down, my relationship with many people are strained. The problem is: They said that behind my back, only between those no good guys. I didn't know exactly what they said, but I can guess is about how I slept around at school or slept to pass the program. What should I do about this? I worried these rumors might follow me when I change job again. And I seriously worry that my significant another hears about this.
