I intend to live forever - so far, so good

You could be completely honest and tell church_35 that you were hoping to go with a date and you are good being friends, but this occasion you really wanted a date. Don't go with her as friends when you know you were hoping to maybe be a little more because then the whole night might be awkward.

It sounds to me like when you asked her she knew there was a possibility of a bf which is why she wanted to wait to tell you until Monday because she was meeting the guy. She probably didn't know how it would go so she was ok to say yes maybe right away, but didn't know if she would be available or not to date. To me, it sounds like the bf is brand new.
