I have been best friends with this guy for four years. We are sophomores in high school. My best (girl) friend tells me that he does like me and that it is really obvious but I really can't tell. He does look at me a lot, and teases me, and comes to my lunch table three times every day. I've noticed that he does keep his body position towards me, but I don't really know what that means friendship wise. My best friend has also said that the other day when he said he needed help with his spanish homework he would look up at me for a few seconds and then look back down at the book.
How can I tell if what he feels is friendship or more? Does he like me as more?
