I did this with a Rothko exhibition at Tate mod earlier on in the year. Got a no (sorry but true) so went anyway. I think it's important to do that otherwise your H will just think you are trying to hard or to manipulate him.

Jody's comments are good - I'm still trying to get to friends - I think I've got there and then he withdraws again. Perhaps I need to watch more closely.
