well, how long have you been with him?
if it's still early days, maybe you're just not comfortable enough to blab everything to him all the time
so no need to worry about that.
if you've been with him for awhile, maybe he just wants you to tell him what goes on in your mind. he won't break up with you if he asked you out knowing what kind of person you are.
but it's true that it depends on what kind of quiet. if you're just not much of a talker, then that's ok
as long as you two don't have any discomforts being around each other in silence - sometimes it's quite romantic taking a walk together and not saying anything at all
but if you're silent in the way that you have nothing to say to him, then you aren't really comfortable with him.
i had nothing at all to say to my ex. we used to walk to school together and i'd be thinking in my head "say something... talk about something... what?" and end up keeping my mouth shut. it's crazy... and now i hardly remember him at all because there was no communication.
so if you find yourself speechless when you're with your boy, just pretend he's your best friend. what would you say in that case?
it's these little things that tell us if someone's right for us or not. if this goes on for a long time and neither of you are happy with it, then maybe it wasn't meant to work, but like i said, it really doesn't mean he wants to break up with you at all
he's just hinting. how else would a guy tell you what he wants in a girl?
