how do you know that someone likes you?  

well maybe his just playing you hot and cold so that you'd feel the way you do.. but if he really likes you more than you like him just keep an open mind let him initiate all the necessary things and dont panic. just give him an accepting attitude that way he'll be more comfortable in expressing himself to you.. but only if you like him.. note, dont let him know you like him a little too much..its usually a major turn off guys likes challenge its a fact

My guy Had to tell me. He was friendly and so was I. He found me nice and I found him very nice but I had No idea he was in love with me until he told me.He was very patient. When we met I thought I loved someone else but gradually I fell for him and now we really love each other. So I wish I could tell you to look for this or listen out for that but I can't.

For me the signs are excess attention and blush

hi. i'm a straight to the point kind of person so if i like a person i would tell him directly. so if someone would say that a guy like me i would ask him directly. but not in a rude way. i usually do it in a teens way. like being so sweet than ask him that question. in this way i won't expect too much.
