it means that he needs time to himself for the weekend :P dont freak
If he says he needs time because his ex is giving him grief then that means he is totally NOT over his ex
It means that he just wants to take time for himself to think about what he wants in your guys relationship. It doesnt't mean hes breaking up with you, he just needs a break.
When he says "You should go out sometime" that means he's sick and tired of you hanging around him. he needs"Guy Time"
he wants to think if your the right one for him to be with and to think about the relastionship
That depends on who dumped who.
It means hes not ready for you yet, your to good for him. he needs time to figure out who he is and what he is ready for
he's either going to ask you to marry him or he just needs to get things oraganized and just needs a break
he is shy or chicken ...(you know what) He dosent know if he wants to be with you At that Exact second or day.. he wants to think about what he wants.
He tells himself thing that aren't true to make him feel better.
It may mean just that, he needs time to think cause he doesn't know what he wants regarding your relationship or it could mean he wants to break it off with you and he doesn't want to say it, cause he wants to spare your feelings.
Coming from a girl it means she needs space. She needs "me" time. Give her some space then lightly ask her whats up. There is oviously something wrong when a girl says "i need time to think."
