Why hasn't a guy I liked asked me out by now?

Why hasn’t a guy I liked asked me out by now? he either doesnt like you or has no idea you like him because I asusme youve never told him right? its not up to the guy to amke the first move, you can as well if you like someone, go up to them and tell them you like them they wont know you do if you just stare at them all the time and guys arnt very good at reading signs or whatever body language you try to give

if we knew what you looked like that would help. Just for instance, if people tell you that you are such a nice person and that you are so sweet and things like that but you look like you just swallowed a hippo or if your not fully umm developed… I guess that is the word. look im not being mean but I just tell it how it is, if you wanna get a guy then act like it, dont be shy and dont be the kind of girl that will do what a guy wants just so she gets attention (those are called sluts). plus you have a lot of life left to live but hey what do I know im 28.
