Looks like H is waking up to the presence of 'competition' regarding the website. This might serve useful in helping him to be spurred on by the prospect of losing you.
I'm curious to see how this plays out, but I would bet it has a very positive influence, as this is different then merely jumping in the sack with someone else, yet can still be threatening.
Like UD, I wonder if a warmer approach coupled with this other programmer's presence might be better. What are your thoughts?
