Are you ok about it because you think it might be a good idea but you still want it to work out, or are you ok about it because you don't really want to be in the relationship anyway?
If she wants a break then give her a bit of space...maybe call her in a few days, asking her if she's ok, if there's anything you can do? Maybe it's a family death or some situation like that. Sounds like it will only be a temporary break.
Even though you say you've been "kinda missing" being single...try and think about it, kinda missing being able to flirt or losing a relationship that could recover...
I'd wait it out and see how she feels in a few weeks. but be there for her over the next few weeks, let her know you care and are there
