Should i expect..

There’s this guy whom i know for 4 years. And somehow I’ve always liked him, but he said he never saw me that way in the beginning. But he always remained special for me and we’ve remained friends. Though i made a mistake by getting into a relationship in between for an year, and later broke up. And i kept him updated with the major events in my life. He was always there whenever i was down and showed care. He’s a kind of guy who expresses very little and is very frank and honest. And since last 2 months he’s talking too nicely with me unlike beforewhen he used to be rude at times). Now he says whenever his mood’s bad, if he talks to me, he becomes normal and that it means a lot to him. I guess all the care and concern i show, he likes it. And recently he thanked me for always being there and that it means a lot to him. I know it can all be just friendship, but I can’t help myself from hoping if there are some chances in the near future of he falling in love. I don’t know, no matter how much I try to control my feelings towards him, cos my brain thinks its impossible, I end up loving him as ever. And to be frank I’ve never felt the way I feel for him for anyone else and never cared for anyone else’s happiness this much! Could you help me analyse all this and advise what should I do.
