They Just Keep Running....

I get to work yesterday, and my boss comes in and tells me that "someone" told her kayleigh and I were being inappropriate, kissing while I was at work, and hanging all over each other. which is so far from the truth. My boss says she doesn't believe it, and that I am professional at work, but she did also let it slip to Kayleigh who told her. Apparently I have done something to offend one of my co-workers and so the shit talking and drama had begun. Its become a back and forth with the girls I work with, and im unsure of what I did. It is no longer comfortable working there. which saddens me.
