I agree - do not initiate or do anything, except maybe to reciprocate as LNA said.
Last year I did give my H some candy he liked (that I had on hand "just in case") but that was it, and that was only because the night before he actually gave me a flowering potted plant (not sure if it was meant for V-Day or not, he didn't say). That is the closest I have gotten to flowers in probably three years.
