So this person was dating a girl named Ruth. Since they broke up, he is no longer with Ruth, which makes him “Ruth-less.” This is a clever play on words, or pun, because “ruthless” is a real word meaning without pity or compassion, and here it’s used literally to mean “without Ruth.”
The humor comes from the double meaning, and it’s likely that the other person had been waiting for the perfect moment to make this joke ever since the breakup.
