I met this man at my workplace about one year ago. I was introduced as he is working in my department. It was almost an immediate attraction at least for me. We locked eyes and he had this goofy grin on his face with his head cocked to the side. Before he left that day he was sure to tell his co-workers within my earshot that he was single and then told me how nice it was to meet me with the same goofy grin. Since that time when he is in my area we often have small chats about his potential career moves, his pets (I had mentioned to another co-worker about my pets and then he brought it up) etc. There are opportunities in our workplace to attend non-mandatory conferences outside of work. I mentioned once about going to one and let him know and so he came too. I was secretly hoping we could talk more in depth as it is kind of difficult at work as our jobs (he and I have the same position) are very hectic making long conversations not to mention nosy co-workers a deterrent. At the conference he sat opposite from me (he arrived after I did) when I hoped he would sit by me. During the conference I could swear he was watching me but I was too nervous to really look his way lol. After the conference was over I waited for him to leave and attempted to walk out with him but he seemed like he didn't want to walk out with me. It was a let down and so I left without him. This confused me as I could swear he liked me but...I try to just leave it and let him do the pursuing if it is gonna happen but nothing more concrete as of yet. I never hear of him talking about being in a relationship when he is at work either. I recently broke down and sent him a facebook friend request one night. He responded almost immediately. He later liked one of my pics. It was one by myself. Nothing more revealing since. No girlfriends on his facebook either. He doesn't list his relationship status. His profile pic is of him alone. I was sure hoping he would message me or something outside of work through facebook so that finally we could communicate more and get to know each other better but nada. Ugh....I have moments where it seems he likes me then sure he really does not. Just recently another outside conference came up. I told him about it. He said he would come. But this time he didn't show up. I was disappointed. I was kind of quiet our next work day together and didn't say much. I left without saying bye for the day. The next work day immediately when he came in he said hello and explained why he missed the conference without any prompting from me. I was over it at that point and was being chatty and smiling as usual. I just like him so much. Not sure if I should just give up.
