Search Results: never felt anything like this

My boyfriend and I broke up several days ago. We were together for 3 yr. I suspected that he’s been seeing this girl we work with and called him out on it. No one knows we’re together because it’s a sticky situation with the hierarchy of our positions. They seemed to be flirting and he was suddenly being rude to me. He has a track record for not being honest with me and so I am already on edge about how close their relationship is. They always sit together and share food, etc. and the day that ended it, he basically ignored me and told me he doesn’t care how I feel. So I walked into their office and told him I’m upset and that I’m done right in front of the two of them. And walked out. This made him so mad that he dumped me. A day or two later, I message him how hurt I felt and he simply replied that I’m too much stress in his life and that he’ll never get back with me ever again. Basically he’s over me. A few days go by and no contact. I get to work and I see him but try to avoid him because I’m heartbroken. He says hi to my colleagues and I. I said nothing. He came back when they walked out of the room, he put his hand on my shoulder and said… I’ll be the bigger person, good morning. I just said hi back. An hr or two later, I asked him if we could talk later. His reply “sure but it won’t change anything.” And I was taken back. I told him that I’m not trying to get him back or beg him to be with me. And then I left. This made me sick to my stomach and to make matters worse, he again is openly flirting with her. So I told him I’m sick and need to go home. He said ok. He came over to me and put his hand on my back and rubbed it saying he hopes that I feel better. It was awkward and totally mixed signals. I finished up my work and left. He texts me, “I hope you feel better” and on top of it, he casually messaged my sister whom he rarely talks to. I’m not sure what to make of this. He tells me he’s done but his gestures and talking to my sister. What do u think?
