Search Results: when girls suddenly lose interest

There is this very attractive man at my work who seemed somewhat interested in me. He would always stare and attempt to start a conversation, but never seemed to have enough confidence to do so. I know I'm not the most approachable person, but I was really hoping he would muster enough courage to talk to me, because I'm to afraid to approach him. This has been going on for a couple months now.

Around the last week of December, I attempted to tell him, indirectly, that I was interest in him, by telling my co-worker/friend about a cute guy in that department... just loud enough for him to hear. He got the message and tried to talk to me later that day. However, I fucked up. As he approached, I suddenly forgot how to speak English and my heart was beating so fast, so I ended up ignoring him.
I felt so bad for humiliating him and I honestly cried over this incident.

Now, he would stare at me from afar, but go out of his way to avoid me. I know I just ruined a possible relationship, and I don't want to lose him. It's been three weeks now and I'm afraid he's going to move on to another girl. I plan on apologizing to him today for ignoring him and telling him that I actually like him. I don't know if he would want to talk to me, but I really do want to fix this. Should I tell him or leave him alone?
