Does this guy like me back?

i recently started reallyyy liking him. so we usually never texted before and today we text for like four hours!! i really really really like him and i get erflies if i think about him. we were talking about how he was at a hockey game and he said it was awesome and i should come next time. he's never said anything like that before! and he also said the fights are awesome and "i would watch ur back". does this mean he likes me back?? i want to ask him to sadie hawkins :)
