Why Japanese guys don't say anything which they want to say??

Some guys text me like I am bored, I wan to go out today, I can't sleep, so I wan to see someone. It looks like they are waiting words which I say do you want to go out with me?? they are such a shy boys.Why they can not say " I want to hangout with you " I cannot understand their feeling.
