Romance and cultural differences in the workplace?

I am relatively new to North America; I come from a French speaking country. I met a guy around 3 months ago in the workplace, which is very multicultural, and noticed he is attracted to me. However, the guy does not talk to me or even worse, avoids me. Once in a month I need information from him to prepare a report. Last time when I went to his place, he looked at my eyes and hold his eyes during all the conversation, he was kind of saying me "I love you" with his eyes. I remembered I twirled my hair unconsciously. He promised me to give me the information the next day but he never did it (he was supposed to go to my cubicle but he never showed up). I tried to remind him about this by trying to call his attention on different ways. Last week we had a get together in the office with the other co-workers and I sat down in front of him. I noticed he was kind of intimidated by my presence. I would just like to know if there's anything wrong with me or if this is part of the North American culture (although where I work is a mix of cultures with people from all over the world; it is a multi-national company). I like him too, but I just don't know what might be happening here. Anyone can help me?
