I think romance is friendship and attraction sort of meeting together and that does influence what I'm writing a lot. I try to establish the attraction obviously but I also think it's important to show the characters having actual conversations about things other than their feelings for each other - and to develop their friendship on the page.
It ought to be illegal for an artist to marry. If the artist must marry let him find someone more interested in art or his art or the artist part of him than in him. After which let them take tea together three times a week.
