I was dating someone from work and all was great. Before we had started dating we were friends and got on so well. However a week before Xmas things changed and he became distant so I called it a day and said let's be friends. He ignored me and refused to talk to me! We went back to work and he didn't say a word. He then decided to reply to my message I had sent 2 weeks previously whilst we were at work. I felt like he was trying to mess with my head! Today he asked if I wanted a drink, I replied no thanks. He then came back again and asked if I was sure and called me by my nickname he called me. He told me when we were dating he only gets the drinks in when I'm there. So therefore I feel he's messing with my head again.
It would be so much easier to get over him if we didn't work together. Yes I know business and personal don't mix! I just feel so upset when I get home. I miss him alot. We got on so well, he became one of my closest friends before the dating. I just feel he is messing with my head though doing these little things. How do I move on??
