I can't think of anything recent -- any decent ones I've watched you've probably already seen. That said, the list of romantic films that I can sit through without wanting to throw up would include Notting Hill, Love Actually, and What Women Want.
I don't know that it really counts as a "love movie" per se, but I would definitely recommend Stranger That Fiction. I enjoyed the chemistry between Maggie Gyllenhaal and Will Ferrell (and no, I can't believe I just typed that either).
