I'm 13 and I like my friend (guy) but he's my best friends ex. I told him I like him and he said he also liked me but not enough to have a relationship that would last. after a while he asked me out. i said yes. he doesn't flirt with me like he used to. (him being a total flirt, its unusual) i think he doesn't like me anymore. should i forget about him and like him only as a friend?
