aw gio =/ everyone is giving you good suggestions, so i'll just give you another so you can feel it out, ya know? some girls are big on safety/security.. they feel like they don't want to be with you, but don't want to say it's over and have you move on just in case they end up wanting you back... which is pretty selfish, but sometimes that's how it goes... they want to keep you riiiight there, just close enough to where you'll still be hangin' around if they decide they want you back... maybe she doesn't know if she wants to be with you, but she's not ready for you to not want to be with her, so she said the 'space' thing... i don't know bud, i'm the kind of girl to really just say exactly what is up, haha.. if i say i don't know, i'm confused about what i want -- then that means i'm confused as hell in my head and i'm confused about what i want, lol.. i've found that when i question things, anyway, it's just not there with that person..
i hope things work out, gio! good luck bud!
