So I decided against showing him this thread, decided it was a bit harsh in places and might get him a bit riled.
So I wrote an e-mail plagarising the best/funniest/wisest comments from here and toned down the harsh stuff. Jist of it was he needs to be very cool, try to figure out if the work thing is an excuse, and to bear in mind that either way, it doesn't look like she has fallen for him like he has for her. Also pointed out the role reversal and parallels with one or two if his previous relationships.
I thought it was pretty good, nad made me look far more witty/perceptive and wise than I am, so thanks for your comments folks. 😀
