My guess (just a guess)...

What you SAID was that you would "give her space". What she HEARD was "I am leaving you"...

And "breaking up" (even though you weren't) with someone isn't something done while at work.

That is how I would (and have, forever ago, interpreted that).

Probably, the more time that goes on, the more comfortable she is without you. What do you want to do?
