I’ve been seeing someone I met on a dating Web site, and it seems to be going well—but I’m still receiving messages from interested women. How do I know when it’s time to cancel my subscription to the site?

The Internet age has created an entirely new etiquette for dating. There are no hard rules, but bravo to you thinking about it before it becomes an issue with your mate. If you are in a monogamous, exclusive relationship, then cancel your membership. If you are still unsure about where things are going, bring it up with your new love. Perhaps you can delete your profiles together to signal you are both off the market.
