Mixed signals... is he interested?
I met a guy mid last year at a mates party. We spent the night chatting; he gave me Poker tips while we were playing, and we cheated our way to winning numerous games of pool (he asked which ball I had, then avoided it on the table).
During the night we discovered we worked together. I thought he was friendly but I went through a messy breakup the week earlier and wasn't looking for anything.
I ran into him a fortnight later at work and spent 15mins talking to him. I developed a crush on him around that time.
Chatting to our mutual friend around that time, he said [crush] had broken up with his gf recently, said he wanted to get to know me better.
After that I started running into him at work about once a fortnight, our chats got longer and one day he ran from what he was doing up to where I was walking to chat.
I saw him about a month ago, just as he was finishing work (I still had an hour to go) and I ran into another room to grab some things after speaking with him briefly. I was expecting him to be gone when I came out but he was waiting by the door. He walked me to my car, mainly looking at his shoes, chatting quietly. After I got in, he walked away, then back to my car, turned around went back to his, turned around walked back to mine then shook his head.
That night I decided I should ask him out and did.
He replied with "I'm sorry but have just started seeing someone so I can't."
When I saw him about a fortnight later, I was busy at work and couldn't talk, but he kept trying to create some conversation.
I haven't seen him since. That was last week.
I have no idea what to make of this. Should I give up on him?
