Are you sure you still want to meet him, knitted.
It's the lack of sincerity that would put me off, to be honest. No one likes the idea of the person they're meeting still looking around, but it's the nature of the game and we all put it to the back of our mind.
But there's just something a bit disingenuous about being so effusive with someone you haven't met and then getting straight back onto the website to arrange more dates and, presumably, make similar declarations.
I suppose, if you're going to be at a loose end otherwise, then it's an afternoon out... but in terms of could a relationship come from this? I'd think not.
