It depends on the reason why she wants to take a breather in the first place - to me it sounds like you need to show her some respect by respecting her space. Some girls don't like needy/clingy guys... some girls want a guy whose strong and independant that they can lean on. To me it sounds like she's feeling suffocated. Give her a few days of space, no contact, then approach her to talk about it. Don't impress upon her what you want, but ask her how she feels, what she wants and listen...
