San Jose, Calif. ? John Claassen wants a date so badly he’s suing for one.

He’s taking eHarmony.com to court, because the popular online matchmaker refused to find him the perfect mate.

Why? Because he is married.

Technically, Claassen says, he is legally separated. But that’s not good enough for eHarmony, which says it is in the business of matching singles “free of relationship commitments.”

Claassen, of San Jose, alleges eHarmony is discriminating against him on the basis of his marital status and is seeking $12,000. He and his wife of eight years separated last May, and he expects the divorce to be final within two months. When he reached marital status on eHarmony’s online compatibility profile, he responded truthfully: “legally separated.”

But eHarmony says its policy is clear: No marrieds need apply.
