How to respond to this?

Me: Hey girl, how's your Monday funday going? Her: Hey! Its ok, pretty busy Me: Yea I feel that. Looks like we both need a distraction from work. Her: I wish I could, I'm working with my boss today Me: I'm busy today as well, how does Wednesday or Friday sound? (Already scheduled date beforehand) Her: I have work on those days. Where do I go from here boys. I feel like I should say something like getting cold feet but I think it's too early for that. Thanks
