Re: Asked my gf for some space.
Well it sounds you're honest to her--in the end there's nothing she can really be mad about because you're being honest.
To me it sounds like she took your word seriously. Which can be good and bad depending on how you handle it. How do you handle it? Well treat it like it's not a big deal but that you understand that in relationships require people to have their own space to think, breathe and relax. The only way relationships can be sustained is if there is a sense of longing for one another--the fear of losing each other is why you come together as well as the reason why you don't spend every day together doing everything.
I think it's important for you to remind her but much more importantly yourself that giving someone space isn't freezing someone out or ignoring them. Giving someone space is giving them the opportunity to still be an individual which in the end helps couple be more defined. As much as you're worried about her, I'd be worried about what yourself in regards to your inner game.
Every moment counts, get out of your head and enjoy it.
