gibson..

I didn't intend to make it sound easy... of course bringing up the subject is going to be difficult... but doing so in advance will really lessen the odds of you coming off like a complete ass. By being honest and upfront about your conception of her being just as interested, you come off like a sensitive guy who doesn't want to do anything that might offend her...

A suggestion for bringing up the conversation... after picking her up at the airport... after all the pleasantries are done... try to start with " I have had something on my mind that I have wanted to discuss with you. For sometime now, I have begun to look at our working relationship differently........... etc..." and go from there....

I assure you that she will respect you more for being a sensitive caring guy.... and if by some chance you have read her wrong... she will be less likely to hold it against you...

Just my thoughts... I wish you well on this...
