A Question of Propriety

What's the protocol for finding that perfect card for your ex-boyfriend? I felt kind of like the whole sending a real, honest-to-goodness, postage stamp and all card was too much. I settled for a lame e-card with a lame message inside about cake and ice cream. It can't be deemed too personal, but it still sends the message that I'm still alive, right? It's all very confusing to remain on speaking terms with someone that you don't really speak to. I wonder what Miss Manners would say?
