How about saying "I'm sorry that you felt that way. However, I need some time and space to sort things out. I hope that you can understand"

Make her wonder...let her pursue you. Right now she's noticing your distancing attitude and the gears are turning, she's a little worried. You have to set an example. If you go back now, in the future she'll know it only lasts a couple of days and you'll go back to her. Don't set that example.

Does she work BTW? just curious if she's sitting at home all day thinking about this stuff.
