I have a new job which I am very happy at, and so far have had positive assessments at. One of my bosses was initially incredibly friendly and extremely complimentary - always telling me every single day how much they enjoyed working with me, what a good job I was doing, rubbing my back, patting me on the shoulders even winking at me.. I wasn't hugely comfortable with all that, but I really liked and trusted them and took it at face value.. but suddenly they have become the opposite- cold and distant and can barely look me in the eye when talking to me. I haven't changed how I act with them, and I haven't mucked up hugely at work, so what's going on and how do I handle it? I hate feeling like I have done something really wrong to cause it.
