I think the same, he only thinks of you as a friend, nothing romantic, girl,
look at it like this, he told you that...so don't sit around and waste anymore
time on him, at least he was upfront and honest, so move on, be his friend, once he sees you have done that, he might decide different. If your always
there and he knows you have a crush on him, well it's not a challenge, so pick yourself up and move on, I would just act like 'see what you missed out on!' Guys usually become interested in something someone else is interested in! If that happens, I would say to him, "I only like you like a brother" Give him credit for being honest, there are some that will just lead us on and on! then never really like us, like we had been hoping! Have fun, it's nothing but a game, so learn to play! Your in control of you and only you! So know what you want , and don't ever accept anything less, or you will be miserable! That is what a red flag is about, if a guy does or says something that you know in your heart is something that you don't like, take that in as a red flag! Don't ever ignore that, or think "I can change that about him!"errrrrrrrrr....wrong answer!!!You can't change anyone, and like I said you will be miserable!!!!
Take care and good luck!
