I feel awkward over a Male work colleague. I believed he was interested, same as what my previous exes did when they chased me (smiles, staires, eye contact, eye brow flash, fidgeting etc, that’s what got my attention. Around that time he did put his arm around me when we were both on a work do as we headed to another bar, even though we hardly ever spoke or worked with each other as I was only 6 months into the job & he mostly usually works from home. Within months of this he asked me for advice about something relating to is new pet dog as I used to work in the trade, now the guy includes everybody in conversation & shows them the videos & updates of his new pet when he calls into the office except me. He seems to have banter with others but seems awkward with me. He regularly notices my fb posts but hasn’t done recently. I’m not sure how to take him, I’m autistic & suffer with anxiety. I feel he has lost interest or I got it completely wrong & I feel so stupid. But he treats me differently to others. He’s quieter with me. Why?
