okay so i knew this guy for a little over 1 year and when i see him in the hallway he looks at me and smiles and winks and when i turn away and look back he is glancing at me he has told several people many things but its like mixed signals.. what do i do from there? we talk a little bit but not much some days he will come up to me and start a conversation but other than that we barley talk he knows my name and everything i just don't know if he does or not...
