Crushed.

So I started to have feelings for this guy at work and I wanted to casually ask him out for coffee. The problem is I have horrible anxiety and it stopped me. Well a couple of weeks ago I started to actually say something to him instead of casually smiling at him when he walked by my desk. I was able to say good morning to him while smiling at him and he would smile and say good morning back. Then last Friday I saw him coming in from picking his lunch up while I was getting on the elevator by myself so I held the door open for him and it was just the two of us and we had a small conversation before getting off the elevator. I said for him to have a good weekend and he smiled and said thanks and I have a good weekend too. Then this Monday when I came in I asked him how his weekend was and he said it was great and asked how mine was and I said it was good. Yesterday we had a special pot luck lunch and I took another leap and asked him to sit with me when he was looking for a seat. We had more conversation talking about our pets and the fact he can cook and I was eating something he made right now and I thought it was great and I told him I liked it and he was so happy I complimented him on his cooking. I then casually went into asking him to have coffee with me and he said yes and I gave him my number and waited. I walked into work excited to see him and discuss plans. I ran into him in the hallway towards the end of the day and casually asked when he would like to have coffee? He then said he wanted to talk to me about that and that he can’t because he wanted to keep it professional between us and he was sorry. My self esteem dropped and now I’m crushed.
