I used to like this guy and i told him then a little after i stopped liking him and i told him but now i like him again what do i do?

Well, if you really liked him and he was cool that you liked him after you stopped liking him and you think he's a nice, RESPECTFUL guy, AND you're old enough to go out AND your parents have agreed that you can go out and approve of him, then ASK HIM OUT! And if you really like him, don't have one of your friends ask him out for you. Guys like it when YOU ask them out, NOT your friend(s). By the way, no, I'm NOT a guy.
